We were using it at the Munich show and playing with it quite a bit. They're not trying to hide it, it's a feature for them. Nothing wrong with that by any means if that's what you're looking for, but it does mean the software has an effect on what gets to the DAC. You can deactivate all DSP in Roon... Correction - I did not check for "bit-perfect-ness" in Tonal because you cannot upload anything else than a complete CD, but I very much doubt it is not (will check with the developer). Anyway, I was hoping someone could give a "rational" explanation (mine were obviously not relevant, and stand corrected). Not a big deal ! Ryan Berry 1 Link to comment

But clearly different player softwares sound different, even when bit perfect. I had a fascinating discussion with one of the guys from Amarra at RMAF last year about this, he was the first person who really was able to explain to me some of the things which matter (not that I remember the specifics). My take away was that there are a lot of very subtle things going on, each one of which may make a tiny (perhaps inaudible) difference, but when you add them all up, you can hear the differences. Suffice it to say, it is worth trying different playback softwares in your own system to find the combination of features and sound quality which works for you. Thanks - that is also the perspective of the person behind Tonal. I wish I could get more specifics and understand what is going on ! By the way, I had some "audiophile" friends over and switched between different players blinded (for them obviously) and they also felt there was a "significant" difference. Perhaps someone like John Swenson could give us some insights ? I seem to remember that the processor's activity causes noise (bursts), and that there are ways to "stabilitze" it, but nothing more specific either. Ryan Berry 1 Link to comment

An audio player uses less than 1% of the CPU time. Even if everything it does is managed to perfection (whatever that means), the remaining 99% of what the computer does is entirely beyond its control. Link to comment
Qhwoeprktiyns Posted July 10, 2018 Share Posted July 10, 2018 That is what I would assume. Someone with a Mac Mini can test Tonal and let me know if I am delirious? Regardless of the specifics of my setup, the idea that the software can have an impact is relatively widespread (not only among vendors of those software) and it would be interesting to either get more technical explanations or some tests/measurements to prove or disprove it.

To clarify, I think DSP is deactivated by default with Roon, so you have to turn on DSP if you want to play with it. At least that is what I recall at the moment.

barrows Posted July 10, 2018 Share Posted July 10, 2018 Well, many in the pro audio field (generally considered to be less "insane" than audiophiles) believe in the sound quality differences between pro audio recording/mixing softwares (recall that Amarra comes to us from the developers of the pro audio software: Sound Blade). Of course pro audio users are not using it in a generally bit perfect fashion most of the time. Of course I use Audirvana Plus and oversample in it, generally to DSD 128 or 256, so not bit perfect at all anyway. This also uses a great amount of processor resources with my preferred filter settings (just an I5 here as well). HQPlayer users will of course use many times more processor resources with Jussi's complex algos (oversampling). I keep that computer isolated from the system via Ethernet though.

Qhwoeprktiyns Posted July 10, 2018 Share Posted July 10, 2018 Yes, those two software I mentioned (zita...) come from the pro audio world as well. Technically, I do not know what is happening but here is a test I came across concerning the networking audio algorithm used which I find interesting: http://qrqcwnet.ning.com/m/blogpost?id=1993813%3ABlogPost%3A33957 Link to comment

Of course pro audio users are not using it in a generally bit perfect fashion most of the time. I have verified that Cubase is bit perfect with default settings. Obviously, a typical production workflow will involve some amount of processing, and this will for sure vary between software packages. 18 minutes ago, barrows said: Of course I use Audirvana Plus and oversample in it, generally to DSD 128 or 256, so not bit perfect at all anyway.

Upsampling, whether PCM or DSD, obviously alters the data (that's the point), and as such different algorithms might sound different. Link to comment

seaharp1 Posted August 17, 2018 Share Posted August 17, 2018 Hi, I need someone with a Berkeley Alpha USB to check their fuse type. Mine blew this morning (2 years use) and it's labeled FS (fast blo). I contacted Berkeley Audio and the part number they emailed me (it's not listed anywhere on the site/manual I could find) is for slow blo. Real world verification would be appreciated by checking your fuse holder (mine didn't have the usual spare). Thanks so much, Larry Berkeley Audio: Description: 5mm x 20mm cartridge 250V .05A Time Lag (Slo-Blo) Mine: F50mAL250V Link to comment

Tomslin Posted August 18, 2018 Share Posted August 18, 2018 And now I can see that we also have one 5x20mm (50mA slow-blow) fuse at the AC socket. In my case it was the two internal fuses that had blow, but of course you should check this fuse in first hand because it’s much easier to replace. Link to comment

Hi, So replacing the Alpha USB primary fuse didn't work.The old fast blow was good...just couldn't see the sliver of wire connecting the end caps.I tried slow blow too. So how did you determine the secondary fuses were blown and how difficult is it to uninstall and replace? I can handle a soldiering iron very well...built many hand wired tube amps. Any advice would be appreciated. I really don't want to send it to Berkeley audio repair and get gauged. Thanks, Larry btw...your pics really helped. Link to comment

Kevin M. Posted February 3 Share Posted February 3 I would say it's still relevant. I just had my Berkeley USB upgraded to series 2. Cost was $220 plus shipping and $30 for new box if you don't have the old one. Berkeley promises improved audio quality. MIne should be back in a few days. I can't wait to try it. Link to comment
Popular Post Kevin M. Posted February 7 Popular Post Share Posted February 7 Well Berkeley is fast. I got the upgraded unit back. The sound certainly changed. I'm curious as to how they were able to change the sound. The easiest comparison I can make is that is sound very analog like now. I'm getting sound much closer to what an album, record, sounds like now. I'll let it break in some and see how it changes. It seems like the sound is fuller now as for frequency balance. The Series one had more of a top end tilt in my system but not as much mid-range as the upgraded unit. The new unit has a more natural sound. PeterG, XRS and Madra 1 2 Link to comment
