RE: The Brennan JB7

I'm busy loading up my new JB7 and must say that I find it all that it claims to be.  Sure - if you happen to have perfect pitch and super-sensitive hearing, sound quality may be lower than you like, but my experience is that most people are fooling themselves if they believe they can tell the difference between compressed and uncompressed files.  The JB7 is a convenience tool and it fills that role very well.

My only dissatisfaction lies with the information management aspect - having chosen to go with freedb, the user-generated database, Brennan have opted for the lowest level of quality and usability.  Frankly, it's a mess.  Clearly designed mainly for pop music, preference is given to artist over composer, so if you want to find all versions of Bruch's violin concerto that you may happen to have scattered over a number of discs - forget it.  By the time the screen shows the performer and, say, the London Symphony Orchestra, there's no space left to tell you whether you are looking at an organ piece or a fiddle concerto. This is because the database uses fixed field lengths so you can't actually get all the data on to the screen. The only thing to do to make sure that the information you need for retrieval is actually there is to input new data for each album after you've loaded it.

Of course, this is not untypical of techie-driven innovations - all the effort goes into the tech and the user end of things is barely touched upon.

RE: The Brennan JB7

I have had one for about 3 months - largest memory.

I have about 900 cds on it - mostly uncompressed.

I think it is absolutely brilliant, but I had to send it away for 4 weeks (!!) after something shorted when I was plugging into Audiolab amp.  Accompanying notes/booklet are/is a bit too brief.  No warning about having everything switched off at all times when faffing about - most people should know this, though.

Whoever says the scrolling to find items is tedious clearly does not understand that you can "search" and sometimes the first 3 or 4 letters you key in will reveal what you are looking for.  doh!

Exciting to play "random", though, all those tracks you never bothered to play over the years pop up and you realise, "Hey! this is good, I've been missing out".   Elgar followed by Chuck Berry, then Lionel Hampton - very stimulating, the surprise, the anticipation!

Now connected to new Roksan Kandy 2 and B&W 603s and I can hear no noise whatsoever that should not be there on playback - as clear as you could wish for!

Why anyone should say do not get it, I cannot understand.  I have been into hi-fi (not audiophile - it's the music that matters) since 1970 and still have the "Which" recommended Thorens TD 150/II I bought that year.  Everything else has been replaced two or three times over the decades, but I have to say, the JB7 is a milestone in listening for me.

About 900 CD cases have gone and the CDs are stored in 2 flight cases bought in recent sale at Maplins for £20 each.  The CD sleeves/info has been filed in alphabetical order in 2 small wooden trays I made.  This can be improved upon, I dare say.

Oh, Brennan emphasis the importance of backup, so the scare stories about "discs not lasting forever...." etc should not concern you if you have bought the Buffalo 500GB disc and copied all you stuff onto it.  Seemed to take about a fortnight, though, running night and day!!

RE: The Brennan JB7

This Forum discussion has all been about the Brennan JB7.  Are there no alternatives?

I had considered the JB7, but was put off by the evident difficulty in labelling and classifying.  I currently have my CDs classified via a database (on Microsoft Access) which allows me to classify more or less as Gramophone does (Orchestral, Chamber etc) and by composer alphabetically (or whatever).  But the system used by the Brennan doesn't seem likely to allow one to do that - e.g. to look at different versions of a particular piece.  And to re-write labels using the text system on the keypad sounds appallingly slow.

Am I wrong?

RE: The Brennan JB7

Well, it seems to me that the Brennan JB7 is a custom device for the older generation who wouldn't have the tech savvy to work out their own solution with a combination of PC work and mediacenter gear. So I couldn't knock it, because I think we all know it's nigh-on impossible to get many older people to adapt... regarding alternatives, although I don't know a custom one, I have seen touch-screen monitors even in supermarkets and I would prefer this with a mini format PC. I don't know enough about audiophile soundcards to comment on that.

Brennan might have thought of FLAC/M4A/APE/WV lossless formats as neither here nor there, but I think he will be forced to rethink this very soon.

RE: The Brennan JB7 RE: The Brennan JB7

I'm afraid I am just the "older generation" you are talking about - I'm 76.  My "tech savvy" is quite limited and it really would be nice not to have to "re-invent the wheel" in technical terms.  (I had a look, for example, at the Amazon reviews of "Squeezebox", which was recommedned by one of the other contributors to this forum, and I found that someone has had great difficulty in getting it to work.)  But I cannot persuade myself that the Brennan will really allow me to access my CD music collection even as well as I now can do so via the CDs, much as I would like to have a quicker way of finding the music when I want it.

RE: The Brennan JB7

Bit patronising to us older music lovers that last but one.  I am 65 and have been working with pcs, photos, etc since the early 90s when the technology was given to us by our employer whose products are all generated by the most powerful computers in the world.  Younger people will also find it is difficult to learn totally new ways of working when they are in their early to mid- 50s.

Anyway, I like the Brennan as I am fairly open minded about new technology - except compression. 

Mention has been made of "lossless".  Is totally uncompressed - which is what the JB7 can do, and in which format most of my CDs are on the Brennan, lossless?  The blurb tells us that this will give a true copy of the original CD.

RE: The Brennan JB7

You need to think of 'compressed' and 'lossy' as different things, since it's possible to have lossy, uncompressed music as well as compressed lossless music. 

However, the Brennan can only do two things - lossless, uncompressed WAV files or lossy, compressed mp3 files.  The former is CD quality (I hesitate to say 'an exact copy', because that's quite difficult to do at a bit level), the latter varies - depending on which bitrate you choose - from between a bit flat (128k) to almost indistinguishable from the original (320k).  In fact, on the Brennan I'd be surprised if you could hear the difference between 320k and WAV.

Rest assured, however, that if you've used 'totally uncompressed' on your Brennan then that's the best quality available (though at the cost of much disk space).

RE: The Brennan JB7

Thanks for that, John - most informative.

I agree, the small percentage of albums I recorded at "the most slightly compressed" (I forget the rating) are good for listening to.

Many of us grew up in an era of listening to music firstly, in the 1940s and 50s as children, on "Medium Wave" via the "wireless".  We then aspired - as we nearly all got jobs then - towards 1960s "hi-fi" where purity and the best possible reproduction of the recording was the target.

Many of those of the next generation after ours may not have heard the following about listening to the radio prior to about 1965.                        MW radio for years had irked millions of listeners with problems like (i) fading signal to almost nothing when your favourite single or concerto was being played (ii) interference from electric appliances like your mum's, or next door's hoover or (iii) interference from most vehicles when they went past your house (spark plugs!) - really loud!! and (iv) background hiss from millions of other sources (v) mono - but that was OK really when you had known nothing else.   My God!  How did we manage!

It is difficult, therefore, for many of my generation to sacrifice "digital space" for quality, even tho' the difference may be inaudible to most human ears.  Just knowing that the music has had something removed is enough for us to want to reject it!  It is like a backward step.  We prefer it "wi' nowt tekkin out" now that technology had given us our first peak in quality a few decades ago.

We do not want to relinquish it for new fads driven by the need to keep selling gear to the masses who can overlook quality for convenience and the need to be "cool" at all times.  However, it has to be said that even we were seduced by the convenience (and apparent improvement of sound by having got rid of vinyl surface noise) of the compact disc.

Going back to quality, I have used reel-to-reel a lot from 1966, and nearly always used 7 and a half"/per second speed - having closely listened to 3 and three quarters and 1 and seven eighths and heard the loss of quality at the slow speeds on a mid-range Tandberg.  You only got 45 mins each side of tape at that speed.  Noisy 1960s and 1970s parties meant, though, you could play a 3 and three quarters speed compilation at 90 mins per side.  Horses for courses.

The quality of reproduction from the microengineered cassettes where, say, TDK SA (without Dolby) runs at one and 7/8ths on a very good (Nakamichi, TEAC) or even a not-too-old budget consumer cassette deck is a different matter altogether as far as "hifi" magnetic tape goes.

So, at the moment, it is fun for me to faff about with reels of tape made as far back as 1976 by playing them on an early 1960s Akai 1721 through a 2010-purchased Roksan Kandy, or to record from the Brennan on to a good cassette to listen to the music via a digital to analogue medium.

Things are technologically very different in each era, but newer and different does not always mean better without question.  Embrace all the media, I say, but you can guarantee that as long as the reproduction of music is discussed, honest opinion, prejudice and bias will always be present in good measure - and thus it has been so for around 50 years, I would say.  

Regards to all and "listen to the music".

RE: The Brennan JB7

Hi,

I am thinking of buying a JB7 with a 320Gb HDD to record most, if not all, of my 1,000 plus CDs at 320k compression.  I have been using PCs for many years and so I am moderately technically savvy despite my 67 years.  But I am concerned that I will find what I want on the JB7.  I have several recordings of different performances of the same works.

For example, I have a CD of Dvorak’s cello concerto followed by Grieg’s piano concerto (played by Guy and the BBC Philharmonic) and each has three movements.  I have several versions of these concerti.  How would I (a) select this performance of the Grieg and have it play the three movements sequentially, and then stop – similarly (b) the Dvorak?

Another example:  I have a recording by Horowitz.  The first 11 tracks are of Schumann’s Kinderszenen, the next two are Liszt piano solos, next come seven tracks by different composers.  The CD finishes with four tracks by Chopin.  How does one find and play these as one wants, singly or in groups and then stop?

How do you elect to play the whole CD?

Thanks for your help

The Wanderer

RE: The Brennan JB7

Like a number of others, I am very concerned about the access to my music files via the Brennan's system and have more or less firmly decided against going for one.

Following advice in earlier posts on this Forum, I have bought dbPowerAmp to rip my CDs and will then set up my files of music by Composer, which is what the Brennan doesn't allow easily.  I plan both to store my files on my computer and back them up onto a Hard Disk.

I am then thinking of using the Squeezebox Duet to play my files, but I have a slight concern about the ability of the very small Duet Controller screen to allow me enough space to "see" my filing system and thus allow me to find the music I want.  Can anyone with a Squeezebox system answer that?

One other question. What format and compression should I use to make the files good enough to listen on my "reasonably good" (but not state-of-the-art) amplifier and speakers.  If I had been using the Brennan, I would have gone for 320 bits/sec.  This kind of description doesn't seem to be offered on dbPowerAmp, which offers Flac, MP3, Wave and some others.  Which should I choose?

It's quite big enough - I've got well over 3,000 folders of music, and don't have a problem.  In any case, you can view your music by, eg, album or artist name, rather than folder structure.

That question tempts the opening of a can of worms best left unopened.

Try different compression types (eg, lossless - FLAC - and lossy - mp3) and different lossy bitrates, and decide at what point you can tell a difference.  It doesn't matter what differences other people reckon they can hear - all that matters is what you can hear.

RE: The Brennan JB7 RE: The Brennan JB7

Thank you, SpiderJon.  That answers pretty well everything, and I am on the point of ordering a Squeezebox Duet. 

But it leaves me with one minor question.  When I contacted Logitech to ask about what the controller screen shows (because the user documentation is very sketchy) they told me that the controller only "sees" albums or Artists and cannot be instructed to look for composers.  So I am thinking of filing my ripped music putting the composer into the "Artist" position, so that the Squeezebox will "see" composers, which is what I prefer. 

Is this nonsense?

It's certainly sub-optimal :-)  

But you don't need to do it, thankfully, because Logitech are wrong.

Whilst Squeezebox itself has very limited built-in browse menus, it does allow 'plug in' modules, such as "CustomBrowse", which (as the name suggests) enables you to create custom menus so you can browse by whatever tag you like, such as "composer", "conductor", "genre", or "instrument"*. 

* assuming, of course, you've filled in tags like "genre" and have tagged your music with custom tags for "conductor" and "instrument".  It'd be too much faff for a lot of people, I suspect. And I don't do it for everything, by any means, but have done it for quite a few things, and find it handy when I'm in the mood for minimalist piano music, rather than romantic tuba or baroque flute pieces, for example.

See, eg,

http://wiki.slimdevices.com/index.php/Setup_new_browse_menus 

http://wiki.slimdevices.com/index.php/Custom_Browse#Available_menu_types

http://wiki.slimdevices.com/index.php/Setup_browse_menu_for_classical_music

It may look rather daunting, but it's pretty easy to set up new browse menus for specific tags.

Plus there's a terrifically helpful user community of Squeezebox users at http://forums.slimdevices.com/index.php so if you get stuck, you can always ask on there.

That's very helpful, SpiderJon.  I now have a  Duet on order and will find a way to suit my own needs, using your links.

RE: The Brennan JB7

Hi!

just joined the forum

I've just purchased the JB7 & are getting to grips with it

Initial teething problems which I hope I can run past other users; firstly to understand why its recommended to use headphone out instead of line out for connecting to the amp. It seems that the volume, bass & treble controls of the JB7 interfere with your amp controls ie. I set treble to max & bass to min in order to regain some amp functions control.

Also, for some strange reason, a couple of ripped cd's play back with a distinct "rumble"

The mp3 "rip" via a USB stick is a doddle & the performance is very good

Perhaps other users can respond regarding these "techy" issues?

In principle, the JB7 does what is says on the tin although it should be borne in mind that it was designed primarily to be a stand-alone device.
