Used Rowland 302 or H2O Signatures CD Direct

According to Rowland,the switch mode ps converts to pure DC.Would this eliminate the need for something like a PS Audio Ultimate outlet or any line conditioning/regenerating devices,in an apartment house setting?Thanks.

The GCC-series of class-D amps by PS Audio have 5 inputs, and other intuitive convenience features that most other amps lack. I don't know how they compare to the H2O's or the Rowlands, but they sound very good in their own right. You may want to check them out.

When I used the Rowlands the PS ultimate outlet did not make any difference.

Muslover --

I might be fairly well qualified to answer your question as I too, own an Audio Aero Capitole 24/192, and I auditioned the H2o stereo amp.

Bottom line -- I was not overly impressed. While the bass was some of (if not THE) best I have ever had in my system, the sound was just "lifeless". It was eminently clean and detailed, but again, lacked dynamic contrasts and full harmonic structure.

As I have read and heard nothing but positives about the H2o's, I and also Henry @ H2o, came to the conclusion that their was some type of impedence mismatch, or some other "lack of component synergy" between th Capitole and the H2o.

My advice -- I wouldn't even audition the amp/s unless you could borrow a decent preamp.

Good luck!

So there you have it. Frankly, it doesn't surprise me. System synergy is important. I have stated it before, when one enters the realm of the H2O, one has bought into a system change, as well. Those who are particularly fond of going direct to the amp, they should look elsewhere for their amp.
