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

Coot, your Placette passive preamp is very highly regarded. You just need to be sure the amp you are getting has an input impedance higher than 20Kohm. Talk to Dennis, maybe his amps really are 60Kohm input impedance which would be perfect with your Placette passive preamp.

Ohm is currently offering a deal on driver upgrades to their 4000 series. I currently have both walsh 4's and 300mk11 any thoughts on the 4000 driver as a replacement for either of these speakers

Peter .. seriously gorgeous. Seems you have taken your Ohms to another level, quite literally.

Regarding the OEM source of the amp modules in D-Sonics amps, if you read the 6Moons review, you'll see that Dennis ain't talkin'. IMHO, that's his prerogative. It's all about the sound. If the amp sounds good, what difference does it make, really, which amp modules he is using? FWIW, my McIntosh C220 works swell with my 10K ohm input resistance Odyssey Audio SS amp, even with 20' RCA runs and the Vandersteen outboard HP filters. No HF roll off that I can hear.

Peterr53: Thanks for the post. Fascinating. FWIW, my Walsh 2000s have no issue with image hieght. In most cases, the image reaches my 6' ceiling. I had Sound Ancors custom make solid, adjustable three-point spiked, cradle bases for my 2000s for around $325/pr. A real step up in imaging and transient detail.

If you click several times on the open case D-Sonic M2 600 mono thumbnail, the print on the circuit clearly says Abletec Engineering. http://www.polkaudio.com/forums/showthread.php?142204-d-Sonic-M2-600M-monoblocks-amp-Pics.
