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

Coot, did the amp come with any documentation like an owner manual? Do you know the input impedance and the voltage input sensitivity for full output? At your normal listening level is the volume control on your preamp set a little higher, lower or about the same? Good write up, it's what I expected, a more control and tunefulness bottom end.

Tobe:

There is a brief manual that covers all M3 amps. I asked Dennis about impedance. He replied as follows "The M3-1500Ms have a 60k ohm input impedance which will assure a high common mode rejection factor."

I find volume settings are no different that what I am used to with the B&K.

Hope this helps. More remarks to follow when I've done more listening. Make that when "we" have done more listening. My wife is more sensitive to pinched, screechy string sound than I am.

Re: D-sonic

I have to renig just a bit on my comment about treble sweetness. Today it is not as sweet as we would like. Still some digital edginess in upper violin range. Overall the sound is not as open as we would like as well, but still breaking in. To be continued...

Coot,

Keep in mind that the new amp is likely revealing or relating what is fed into it differently than before. If "digital edginess" is heard, I'd say it is quite possible that changes to input might address that. My Class D Bel Cantos are very revealing. I hear major differences in that regard even with changing ICs. Also definitely with DACs. Not so much on digital source, but my digital source is Wifi connected to remote music server with Toslink connection out to DAC. USB connections alone can vary quite a bit case by case as well as I understand it, though I have no experience with those. Personally, I would steer away from USB conenctions myself unless willing to experiment with different implementations.

Just some thoughts to point out that any new issues heardwith new amps may or may not be amps fault. A/B comparisons/testing with different gear might be needed to sort through.

That is my favorite version of St. Saens ORgan Symphony as well. Not perfect but a very fulfilling analog rendition no doubt.

Also should point out that break in time may be needed with many Class D amps from what I read, so might be wise to get through that first before changing opr addressing anything else. My Class D amps were acquired used and I did not find they changed much over time by the time I had them. ALso, they sound good immediately from a cold start when I power them up, though I do tend to leave them on most of the time in that they do not draw much power idle.
