I am extremely happy with the Classe' line of products. I have looked at Levinson, Krell, Atmasphere, etc. I have always found the Classe' products to be just as comparable if not better in build quality on the Omega line of products. To give you some history, I have full range electrostats manufactured by my Uncle's company, SoundLab. First, I started off with the Classe CA-201 in 2000. I felt I was missing the detail and fullness that my speakers could produce. I then traded the CA-201 in for the CAM-200 monoblocks in 2001. Very good monoblocks with excellent bass and midrange. However, the highs seemed to be rolled off and a little brilliant and more importantly felt that I was missing the ability for this amp to point out finite details and accurate sound staging. I demo'd the CAM-350s but felt they were beefed up CAM-200's as sonics and soundstage were exactly the same. As a side note, the only difference between the CAM-200 and the CAM-350 are the power ratings and the toroidal transformer sizes: 707 KVa for the CAM-200 and 1200 KVa for the CAM-350. My dealer recommended I look at the Omega line if I was particular in finding what worked well for me and my speakers. After listening to the Omega series I was hooked! The first thing that I noticed was that all of the detail and the frequencies were represented very accurately. The Omicron mates extremely well with my SoundLab M-1 electrostatic speakers. I am hearing my CDs in a new light and again the imaging, the highs, bas, and mid are near perfection.
Of note, I found no discernable differences in sonics and soundstaging between the flagship 450W Omega dual monoblock and the 350W Omega Omicron dual monoblock. I also did a side-by-side comparison of the Omicron and the Levinson No. 33. I felt they were on equal playing fields on performance. Due to phenomenal deal I went with the Omicron. Please keep in mind that Classe’ has launched their Omicron monoblocks at the 2003 CES show in January. Since the Classe factory had 4 new Omicron units left they were willing to slash prices at near cost of $5900 vs. the original retail price of $12,000 USD. In addition to the excellent price I received from my dealer (HiFi Centre) he drove from Vancouver to Seattle to personally install the unit for me. Great product and service!
Before purchasing the Omicron I compared it against Krell FPB 350, Mark Levinson No. 33, Atmasphere MA-1 MKII, CA-201, CAM-200, CAM-350, Bryston 14B SST and found the Omicron and the Atmasphere to work best with my full range SoundLab Electrostat speakers. The decisive factor between the Omicron and the Atmasphere was the price.
BTW...all Omicrons are MKII units. No MKI units were ever released for sale and that Classe decided to move to an MKII release of the product prior to public launch. This is according to Classe' customer service.
