The specs were put on this site when Axel sent them to me..
That's great - for the 6 of us who read this thread on June 27th.
I stated it was the best solid state amp I have heard so far and that means I thought it was better than the V200.
Again, great info for the folks who follow this thread (and remember that you used to own a V200).
This was a honest review with no regard to sennheiser having any input except to check my facts and nothing was edited. The only Spec that Axell Grell sent me were published here in this thread and everyone seen exactly all the information I was sent. Guess you missed that post. I didn't say it before, but I think the fact that Sennheiser vetted your review before it was published reeks of impropriety. As for mssing your post, actually, I was one of the 6 or so people that saw it. Thank you! Unfortunately, all of your loyal followers who, for whatever reason, missed your head-fi post on June 27th still don't know how many opamps are used, what the input and output impedance figures are, what DAC chip(s) are used, what the power ratings are into 16, 32, 150, 300, and 600 ohms, and if the USB is asynchronous. Also, I'm just wondering why you only published the 50 ohm power figure in your "review" when this amp is supposedly optimized for the HD800 (a 300 ohm (nominal) impedance headphone)? But that's just picking nits so you don't need to answer that.
I stated in the review it was op -amp based. i have no idea what capacitors were used because sennheiser did not share any of that information. Whatever was given to me is posted. The op-amp design is in the review as well as the maximum power output. Those are also on this site. I have no idea what circuit it was because they never shared that information or anything else about negative feedback in their design. I wrote the review based on what I heard because in the end thats what its all about anyway. It sounds good except for the dac issues which were mentioned in the review. It also usually take me at least 60-90 days before I get the reviews written.
Exactly my point. Over 3 months and contained in two pages, basically all you said was, "it sounds good." Sunshine and rainbows are fine to a point, but where's the beef? Frequency response? DAC performance (ringing, filtering, etc.)? Phase response? Channel balance? Gain? Jitter? S/N ratio?
You yourself said, "if your (SIC) spending 2K on a product it would be nice to know...I believe the majority would like to know what the specification of the product are and that IMO is not pointless"
I'm sorry Frank, I didn't mean to make you defensive. I'm just expressing my frustration at trying to find out about this amp. You said several times that you were writing an "official review" and that you were waiting for specs from Sennheiser. And now that your review is finally published, we still don't know Jack about this amp and DAC.
