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

Interesting you mention Bryston. I am looking to replace my B&K with a new amp. So far I am considering Bryston 4BSST2 (300W 8Ohms)-$4995, Van Alstine 600R (300W 8Ohms)-$3500, D-Sonic M2-1500 (1500W 8Ohms)-$2800. Not sure I want to blow the extra $$ for the Bryston. Right now, looks like I will try the D-Sonics. Speakers are Ohm Acoustics 5000s. Budget: $5k max. Any comments appreciated.

Question WRT Ohm 5000 power and bass. It has ben said that adding wattage may obviate the need for subs. I need lower bass, not just firmer or louder bass.

Adding watage alone with any speakers only means they should play somewhat louder with lower distortion. That is usually a good thing in regards to bass, especially at higher volume, but does not mean anything necessarily in terms of better frequency response at lower frequencies. Two similar wattage amps will likely perform differently at the lowest frequencies. A lot has to do with the impedance load of the speakers and the amps ability to perform accordingly, especially at lower frequencies. In general, smaller speakers that can extend lower will require a more robust power amp to deliver the current needed into lower impedance loads that typically occur at lower frequencies in order to have good low end frequency response. Of course this is just a general pattern, YMMV depending on amp, speakers, room acoustics, etc.

Thanks Mapman. That helps.

Coot: FWIW, I too have my eyes on that D-Sonics amp (although financially, I am farther away from a purchase now than I thought I'd be). I did ask John Strohbeen about that much power into the 2000s. His reply was, "go for it, but keep an eye on the volume control". IOW, don't turn it up loud, then leave the room for an hour. That much power could potentially overdrive the speakers. But if you are in the room, it would be obvious that the level is excessive. As for the bass, I would think the 5000s, properly driven, will have all the low end extension you desire. That said, I do have a pair of powered subs with my 2000s. Truthfully, I might be okay without them (the bass on the 2000s is pretty good), but I doubt any loudspeaker can move as much air in the bottom octave as my pair of powered subs. BTW, the D-Sonic is more like $2400 than $2800 (unless you are Canadian, I guess).
