Berkley Alpha Reference DAC (mini) Review

Great to know! The BDP-2 is such a great sounding server. Are you using the digital balanced into the BADA? If so, what brand cable?

Funny enough, I have yet to do the Manic Moose (MM) upgrade as well. With MM the BDP-2 will play DSD via USB. Maybe I need to do the same and get the stick from James and Bryston.


I use the BNC to BNC connection on my Baetis server, as the older model I have does not have balanced digital output. The new Baetis Reference Server has balanced digital out.....but it's 12k. I do use the balanced digital out on the Bryston BDP-2. I have a Nordost Valhalla and Stealth Audio Varadig Sextet digital AES cables that I use. Silnote Audio's Morpheus AES cable also does a great job with that combo.

Have you tried the Shunyata digital?

Back to the BADA Reference...:D

I have their digital A/C Zitron cable. But the Stealth Silver M-7000 cable demolished the Shunyata. I really wanted the Shunyata to be at least close, as it is so much more manageable (read pliable) then the monster Stealth cables. But I could not give up that much SQ for ease of use. I think I tried a couple of Shunyata's digital cables via the Cable Company. It didn't work out.....whatever models they were.
 
Main system as currently configured: MBL 101E's / Pass XS-150 Monos / Brekeley Reference DAC / Bartis Server / PS Audio P-10's / (2) REL 528se Subs / Stealth Audio and Dave's Cables


Secondary System: Spatial Master Speakers / D'Agostino Mono's and preamp / Direct Stream DAC / Bryston BPP-2 / PS Audio P-10 / Nordost and Dave's cables
very nice.

Has anyone out the BaDA ref next to the Nagra Hd. I have heard the Nagra and was impressed. Curious how it stacks up to the BADA ref.

we need a high end Dac shootout !


1) BADA ref
2) Nagra HD dac + mps
3) Trinity
4) EMM DA2
5) Boulder 2120

there can only be one....

.

it will be indeed VERY interesting since they take 2 totally different approach: NAGRA convert everything to DSD while BaDA play only PCM !
 
Any updates on how the Berkeley RS is breaking in?

I'm about to "pull the trigger" to upgrade my digital front end. The Lumin S1 and the Berkeley RS are my two finalists. As much as I would like the Berkeley, the fact that DSD is not avail through it is a significant drawback - at least in the configuration I would use it with the Bryston BDP-2.

In contrast, the Lumin S1 does offer the flexibility (PCM & DSD), looks, ease of use and excellent sound.

Why don't you consider the TotalDAC D1-Dual isntead of the Berkley ? and you can add to it a TotalDAC D1-Server. It is supposed to be superbe sound, do DSD, and is supposed to offer a silk but precise signature (like most R2R DACs). I may get this combo soon....

I'm looking at the TotalDAC server for the Devialet.

Thx B. I'm down to these two options. I did look at it and read the reviews - very compelling.

I tried the TotalDac combo recently, with a big Ayon amplifier and TAD speakers. It was quite remarkable, though I wonder if it was worth the 15k it goes for (I have yet to hear a streamer that I don't find renders a "noisy" sound with an artificial liaison between the notes and a similar sound from one recording to the next -- and Mike, I'm finally due for a Lumin demo at my showroom in two weeks).

I love my Berkeley Reference DAC. And with JRiver, all you need to do is pre-convert all your DSD files to PCM and store them like that on hard drive.
 
Just as a side note in regard to the Berkeley REf. dac. Chris Connaker of computeraudiophile now uses this DAC without a preamp. I think this has 2 potential values for our consideration. Sans preamp may allow more people to financially add this dac to their system after selling their preamp. Secondly, assuming Vinyl is not a big part of your listening, doing critical listening without one additional interface and cables and its sonic signature may provide even more accurate and hopefully listening pleasure. I hope some of our members will give this approach a shot. I personally like my preamp and dac combo but perhaps a ref. dac like the Berkeley may be a totally different animal that excels going directly to amp.

I now have the S-1 Lumin as well as the Berkeley Reference and Lampi 7 dac in house. First off, the Lumin is awesome to use. The software is a dream come true. It does 1X and 2X DSD and will soon be a streaming champ per Mike. So it is overall a real winner in my book. The Berkeley is better on redbook. Any audio adjective you wish to compare, the Berkeley does it better.....maybe 10% better. But I have not yet found the digital NIRVANA that Robert Harley and others gushed about. The Berkeley DSD playback via conversion through J River sounds as good as the Lumin on several tests. So no winner there.
The Lampi 7 is the DSD champ in my book so far. It has a real organic truthfulness to my ears, that is more faithful to the real thing. The tubes give it a very romantic and engaging sound. I believe the Berkeley may be a tad more resolving, but not quite as enjoyable as the Lampi.
At this level, there are no losers. The Berkeley price is still un-justified (IMHO) at 16k, without world class DSD. The Lampi is a great DSD dac and a very good redbook piece, which has several price points to choose from. And the Lumin is a sit back and enjoy the music player, that gives you probably 90% of the best possible sound quality available. The Lumin has a couple of different models available at differing price points. So the best choice comes down to what is most important to the end user.
I myself am going to keep all three. I will use the Lumin in system one.......and hand off its redbook playback to the Berkeley dac. In system two, I will use the Lampi dac. I do have a smaller third system that I use the Oppo 105D player for SACD/redbook/DSD playback. It also picks up the Lumin L-1 storage drive very nicely, via the network connection.
Of course these observations are very system dependent. As always, I suggest you perform an in-home demo before a purchase.

Happy listening.......Jerry-
 
Great feedback Jerry. You have the three top digital pieces available today! Sweet.

I'm glad you love the Lumin.

any biases using these 3 units with and without a preamp?


Only the Berkeley has volume control. My Lampi does NOT have a preamp, and neither does the Lumin. With the Pass XS-150's/ MBL 101E's/Berkeley combo........I prefer a preamp. With D'Agostino mono's/MBL's/Berkeley combo........I prefer a preamp. But, with the Cary 211FE monos/Spatial Masters/Berkeley combo........I prefer no preamp.
Previously, I also found I preferred no preamp when using the Direct Stream with the VAC 200 mono amps. On solid state combos I tried with the Direct Stream.......I always preferred to have a preamp in line.
So, I found a better synergy using a preamps on an "all solid state" systems..........and NO PREAMP with tube amps. As always, YMMV.
 
Lumin does have volume control on the app, but it's not recommended to be used. I've used it direct and it was fine, just have to make sure you don't accidentally turn it up to quick.

Um, it's called the Reference, not the All Purpose.

Have you read the interview Robert Harley did with Michael Ritter? It follows the review of the Reference DAC in the October TAS. Michael is well aware of the marketing benefit adding DSD capability would have bestowed but is absolutely convinced that having the DAC chip do double duty converting DSD to PCM would have a detrimental effect on the sound. He could have added DSD decoding for almost zero cost, far less than the price of the JRiver license they include with the DAC so you can convert your DSD to PCM. Berkely is pretty fussy about the DSD > PCM conversion and was going to write their own software for it, but found that JRiver was "doing it right".

Regarding the USB input, Michael had this to say: "There may be a time when it makes sense for us to introduce a lower-cost DAC with a USB input, but when you're shooting for the ultimate in performance, which is what we did with the Reference Series... you absolutely don't want to connect the DAC directly to the computer or router. They have large amounts of electrical noise that gets injected into the DAC's ground, or the noise is capacitively coupled through the input. A separate isolation/reclocking device [a USB to SPDIF converter] for computer-audio playback is essential if you're going for the state of the art".

Howard,

Esoteric manages to include an inboard USB connection and DSD capability in their reference level Digital Players and DACs without any sonic degradation. I would hardly consider this all purpose, more like a basic requirement these days.

I guess Mike did mention the volume control, but I heeded the warning. I did not try it. If the manufacture doesn't suggest it, I avoid it.
