Ohm Walsh Micro Talls: who's actually heard 'em?

Good point by Tobe. Not usually a good idea to plug high power amplifiers into anything other than the wall outlet. External power conditioners usually become a bottleneck for optimal amp performance in that they cannot deliver the power and current needed. Those that can will be quite large and heavy and expensive to boot and better results may or may not result still.

Thanks, guys. Done.

Final report on d-sonic M3-1500s. To make it short - They're going back. After 100+ hrs, shrillness still there - I mean "gives us headaches" shrill. Good kick in the low end, but that's all the good I can say. Connected my new W4S DAC2 DSD-se hoping to make it better. No change in sq al all. Put the B&K back in. The bass is deeper and sound is cleaner with more detail throughout with no digititis. I am v-e-r-y happy with this DAC. Sorry the amps didn't work out but glad you suggested to try a better source, Mapman! Later I may try the AVA 600R, but we will live with the B&K for awhile as it has whetted our appetite for deeper bass, etc.

Coot, thanks for your honest opinion. To hear shrillness coming from your Ohm speakers really did concern me because Ohms have a very mild manner tweeter. I'm shock but appreciate the heads up.

Coot .. as I'm sure you are aware, the W4S amps have garnered much praise in their latest iteration. Just thinking out loud here but perhaps you should consider them as well in the future. The synergy offered by using products from the same company can be compelling. Congrats on the new DAC.
