If you already have a good dac, then I would seriously look at the Audiolab 6000CDT transport (about $550). This machine is simply amazing! I've compared hi-res (including DSD and hi-res PCM) files with Redbook CDs of the same material played on the Audiolab and they sound virtually...

Some very strange things happening. I still had the old Resonessence website bookmarked and out of curiosity, I clicked on it again and much to my surprise, a new Resonnessence Labs page appeared. It bears no resemblance to the old website although a lot of the material related to filters...

It's too bad about Resonessence but I'm likewise not too surprised. I bought 2 dacs from them in the past - Invicta and Mirus Pro - and never had any QC problems. However I was frustrated about a minor issue with the Mirus Pro cutting off the first microsecond or two of FLAC files - they...

New and very happy user of the Benchmark HPA4 and DAC3 B combo! I had been enjoying the HPA4 with another dac (Resonessence Invicta) but based on the reported synergy between the Benchmark amp and dac, I decided to replace the Invicta with the DAC3 B. The improvement in overall sound quality...

I have been using both the Danacable Lazuli Reference and Kimber Axios cables for my Utopia, and agree that they are both excellent. I decided to keep both since my preference for one over the other seems to vary. However I disagree that the stock cable is not very good -- in fact, I think it...

I doubt that Resonessence is just treading water, especially in the fast-paced world of dac innovation. I do feel that the products they have developed to date are still quite competitive and among the best available, especially within their given price range. I've had a Mirus Pro for just...

I would add the new Benchmark HPA4 to the list of highly recommended amps for the Focal Utopia. The Utopia/HPA4 pairing is magic - easily equal to the GSX MkII, which I have also owned at one time. In fact sometimes I feel that the HPA4 may slightly improve on the SQ of the GSX, but this is...

Several months ago, I did get the 7.0.2d firmware update sent to me via email, and it fixed the problem with the missing start of tracks perfectly. However I'm somewhat surprised, at this rather late date, that the update has not yet been posted on the Resonessence website, although perhaps...

To add to this very comprehensive list of amps to compare with US4+ -- Benchmark's new HPA4. I just bought one, and it's a really top-notch amp -- easily equal to the GSX MkII and, in my opinion, better than the Pass HPA-1 (I've had both).

Brief follow-up to my initial post on HPA4. I now have about 80+ hours on it, and I think the "burn-in" period has probably made a slight but audible difference. My initial impression still holds though - it is one of the best (if not the best) headphone amps I've ever heard. I continue to...

I've been using my HPA4 for about 3 days now (picked it up from UPS on Monday). It was very well-packaged and included all accessories and owner manual. No problem at all setting it up - basically a "plug and play". I did read the manual online before getting the amp, but all the controls...

Well, I had the GS-X MkII and then purchased the Pass HPA-1. I did have both for awhile, and although I very much liked the GS-X, I thought the Pass worked for me a little better overall, so I sold the GS-X. Overall both amps are very good -- both are resolving, dead quiet, and generally...

I have a Mirus Pro (not Signature) as well, and have also experienced the same problem (cutting off a few ms at beginning of track). Fortunately this doesn't happen very often but is annoying when it does. Since I only use SD cards, I can't verify whether this occurs with other inputs...

I wonder if Resonessence Labs will be able upgrade current Mirus Pro units to the Signature Pro level? I'm sure there are a fair number of Mirus Pro owners (like myself) that might be interested, especially if it turns out that the sonic improvements are substantial. Unfortunately I gather...

I had been using the Focal Utopia's stock cable as well as the Kimber Axios, both of which I thought were "pretty good". Thus I was skeptical as to how much improvement the Lazuli Reference would actually be - however, seeing that they had an excellent return policy, I decided it was worth...
