This is a mini-review. For 3 years I have been listening to my LA7000 balanced headphones using a Meridian 808.2i CDP as source. I felt so lucky to have been able to purchase a B-stock unit new for way below MSRP, and after the warranty service replaced the disk drive, it worked flawlessly and made beautiful music.
But I was missing the digital age of high-res, so in December 2011 I finally bought the Berkeley Alpha DAC2 and USB interface, widely reported to be one of the 2 or 3 very best high-end DACs. Driven from a PC laptop loaded with JRiverMediaCenter, reported in TAS as the best software for PCs, the Berkeley DAC2 revealed strikingly fine details with refinement and sophistication, from CDs ripped to WAV or from downloaded FLAC files at 88.2 or 24/96 from HD, Linn or Chesky using JRMC. And I could drive it using the digital out from the Meridian, which while playing Red Book CDs upsamples to 176 and outputs SPDIF at 88.2.
But no matter what data I gave it, I found the SQ of the DAC2 emotionally lacking, not quite analytical but not really alive. In fact, I much preferred the SQ that the Meridian produced from CDs to the SQ of the DAC2.
I had read and kept the first column on the Bricasti M1 DAC by John Marks and then the review by John Atkinson in Stereophile last year, and when I digested the very clear recommendation in the second John Marks column in the March 2012 issue, I knew it was time. (If you haven't read these, then I highly recommend you do - just google "bricasti stereophile".) On the Bricasti dealer webpage, I found the name of a high-end audio dealer I knew and trusted, Jim Riddell of Sounds Real Audio in Colorado, and it turned out he had a demo unit I could audition. Well, the short story is, he never got it back. And I am enthralled!
The Bricasti M1 is the best piece of audio electronics I have ever heard. It was designed to make music. The entire unit is balanced dual-mono --- the two channels have separate power supplies, separate dual differential DACs, separate clocks (which are synced by a SPARC) that are virtually jitter-free (~6ps), separate balanced and unbalanced analog output buffers, and so on. The music that emerges is completely detailed and completely alive --- totally transparent, utterly micro-detailed and micro-dynamic, liquid and smooth as can be, vibrant, palpable and more realistic than I have ever heard before.
When it arrived, it had only the linear filters described so well by John Marks and John Atkinson. When I emailed info@bricasti.com with a couple of routine questions, I heard back from one of the owners, Brian Zolnar, who spent a considerable amount of time educating me on how to use the M1. For example, I was making a serious no-no feeding the DAC a half-interpolated SPDIF data stream from the Meridian, and when I followed his recommendation and fed the M1 straight 44.1 SPDIF from a 20yo Rotel CDP I had in the closet, the SQ was enormously improved. And finally, I was hearing music from Red Book CDs that was of VASTLY higher quality than the Meridian produces. The DAC2 was left in the dust (and has already been sold).
AND THEN .....
Brian told me he had an upgrade chip with some new "minimum phase" or apodising filters. It arrived here a few days later, installed itself easily, and suddenly the SQ of the M1 became even BETTER --- in fact WAY BETTER, better timbral detail, better depth and realism, better decay and ambient details, and most of all better punch and dynamics, which was the only thing a friend who had visited had said it lacked (he likes electronic rock at 100dB!).
In addition, it now has a front panel digital level control (from 0 to -60dB, and Brian says the internal calculations are at such a high resolution that there is no bit-loss until it gets beyond -24dB) and phase inversion. Brian says an IR remote with these capabilities, along with filter selection, of course, could be available as early as June. I can't wait!
Currently, I am enjoying hearing for the first time all of the music hiding in my favorite disks in a very large CD collection. Really. And really enjoying them! For example, the EMI Great Artist re-release with Hans Hotter singing "Ich habe genug" (Bach Cantata Nr. 82) sounds fresh and and deep and stunningly real, and it's easy to hear the greater vitality in his great voice in the Brahms Lieder that he recorded earlier in the 1950's, and even more clear in the version of Brahms Requiem he recorded with Karajan, Schwarzkopf and the VPO in 1947 (which with the M1 is just breathtaking, esp. Schwarzkopf). Or, the Sony CD of Schubert's Great C Major Symphony with G Szell (whether you call it 8th or 9th), which I've listened to with the M1 already 3 times - unbelievable presence and clarity and such sforzando! Most amazing is the way the M1 presents the female voice or an a capella choir -- I have been thoroughly enjoying re-experiencing Robert Shaw's many disks (esp "O Magnum Mysterium"!), as well as re-living the original heart pangs I felt (x10!) when I first heard Cecilia Bartoli's initial recital CD or Sophie Karthauser singing Bocccherini's Stabat Mater (oh wow).
Here's my 2 cents on the many filter choices that the M1 now offers --- after much comparison listening, using the same 2-3min tracks with every filter, I decided to forego the various improvements in stage proximity and perspective that are available, because I felt that the best overall balance and the most complete presentation is consistently produced with Minimum-Zero, and I leave it there all of the time. While listening, I use the front panel for level adjustment, which follows in real time with no lag and without clicking "enter". And I'm listening with Beyer T1's (re-cabled by Peter at DoubleHelix with RS UP-OCC, which opened up beautifully after ~400hrs use) driven by the "quad-mono" Rudistor RP010B, using JPS Aluminata i/c's on loan from thecableco (and I will HAVE to shell out for these!).
SUMMARY --- IMHO, the Bricasti M1 is the best piece of audio electronics I have ever heard. To my ears, it produces realistic SQ and deep musical enjoyment that is at least as sweet as, and in several aspects far exceeds, any analog system I've ever heard, including the vinyl rig that now sits in my closet. I hope you find an opportunity to hear it soon. It has honestly changed my audio life, and I am incredibly happy being able to experience extraordinary music with the M1 out here in the Sonora desert. It's like having a prime seat in Avery Fisher Hall or the WDCH every night! Absolute top recommendation!!!
Happy Listening!
