I think that an amp that offers no feedback is far more accurate than one that doesn't. If your are seeking a very neutral amp that has the front end to support it, then I would strongly consider the Sim W-10's. I have heard that the Parasound is a good sounding amp, weather it has garnered the same International press as the Sim products is probably worth researching.I have had the pleasure of having a older W-5 in my system and was amazed at the sheer musicality that it offered.I also was shocked at the dynamics and the resolution it was capable of, it threw a soundstage that you could land the Enterprise on.The only concern is with the rest of your system, if it is on the hot side then you may not like what the Sim shows you.I hope that one day I may also own a powerhouse pair of monoblocks, since my speakers absorb quite readily. Hope this helps and good hunting-Dennis
