Review: Berkeley Audio Design Alpha DAC Series 2 DA converter


Category: Digital

I was itching for more reports on the Alpha DAC Series 2 other than the Robert Harley review in TAS. Personally I get the feeling he is a little too much "in love" with all the BADA products and wanted some more first hand accounts, but they are few and far between. I had owned and loved the original Alpha DAC for 3-4 weeks (I am a gear whore) until I snatched up this Series 2 here on the 'Gon and so I was lucky enough to have them both at the same tame for comparison. This review is more of a comparison of the Series 1 vs Series 2 versions of the BADA.

Actually I am lazy and not very articulate, so I am just going to post my notes here. I find discussions more informative anyhow so I will do my best to answer any questions that may be posted.

- 1st impression softer, less leading edge definition, more "analog"... only "better" depending on taste.
- Wait, notes actually rounder, more depth - circle vs sphere.
- Imaging more solid.
- More detail, nuances, delicacy, air, openness, texture.
- Moderately wider soundstage.
- More liquid flow with saxophone.
- Sweeter highs.
- Hear snare drum head skin more as opposed to chains with S1, more pop.
- Cymbals more splashy with series 1, bit glassy in tone by comparison.
- Toms more resonance and body
- "Fat bass" referred to in S1 review better defined, tighter.
- Accompanying piano in jazz ensemble better delineated.
- Better balance among instruments in ensemble. Series 1 ride cymbal overpowers piano.
- Better sense of vibrato with strings during "normal play" (and not just with long sustained solo notes).
- Kravitz electric guitar esp. good - more creamy, dense grunginess - very distinct in soundstage.
- Voices more focus.
- Just more musical.

The Series 2 Alpha DAC retains very much the same basic tonal character of the Series 1 but at the same time is very much improved in the ways stated above. However, I must say it took me a little bit of listening to definitively prefer it to the Series 1. In the very beginning I thought it might have sounded too soft with less of a direct vibrancy about it, but it didn't take long to realize the Series 2 is just superior. One way to describe that main difference is that the images with the Series 1 are more carved out (but NOT hard or shrill!) whereas they are more "lit from within" with the Series 2. I think some may actually prefer the Series 1 but the strong majority would take the Series 2. The Series 1 is still a great DAC, but the Series 2 is significantly more refined.

When I first replaced my Bel Canto DAC3 with the BADA Series 1 I was quite surprised that they shared a lot in common, with the BADA being more refined and deeper tonally. If I had to put number to it, I would say the BADA was about 20-25% better than the DAC3. With the Series 2, I now put that number at about 45-50%.

If you can swing it, the upgrade will most likely be very much worth your while...

*** I must note that the Series 2 I purchased was slightly modified with the stock fuse having been replaced by an Audio Magic Liquid Nano fuse and some cork added to the chassis for dampening. I don't know how much this contributed to the sound of my Series 2, but I do know it sounds damn good!

I had his DAC in my possession for about a week and returned it feeling pretty unimpressed. Easy going sound with you could say "analogue" presentation but it just didn't do the trick in my system.
I do admit I was coming in with big expectations based on raving reviews. It's got a little dryer presentation like most solid state dacs, and it's got really no punch to it, so anybody who listens to electronica beware. My dealer here sweared by it, and was curious what came pretty close to it for much less money...I brought over my 1500 Red Wine Isabellina with some midrange oriented tube which I think sounds just as good, if maybe the control of the frequency extremes is not as good (different tube would make it sound just like Berkeley). Mind you, even though Isabellina has tube, it does not have the "lit up from within" sound like Ayon cd-5 that I have on loan or Lampizator. Anyway, I think even the dealer had to admit that the Isabellina for less than 1/3 performs very well.
Funny that you say that because it was on my list, but it seems like they are "flying off the shelves" and with no local dealer, it turned out to be too much of a hassle to arrange a home audition. Maybe in the future...
