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

D-Sonics are worth a try IMHO.

More recent models are better suited for use with a tube pre-amp I recall.

Current delivery/robust power supply is more important than just power/watts.

Using subs should offload low bass from mains and reduce demand on the main amp so lesser amplification might be used if a good sub or two is in the equation.

IMHO, OHMs right sized t o the room with optimal power amplification do not need subs, but using subs is certainly an option if desired.

I should add that music is mostly classical of which a large portion is pipe organ and large scale orch. - sometimes w/organ & chorus (ie, Mahler 2).

With my B&K when I turn it up, sq sounds a bit choked and closed in. On chamber music sq is wonderfully rich and natural.

Coot I think 180 wpc@8 ohms is enough. Before I got my McCormack (250 wpc), I was using 130 wpc amp and it sounded nice. The extra power was noticed primarily in the deep bass response, and you should be fine, particularly with classical music. Also remember that Ohms have an impedence of 6 ohms, which means your 180 watts will be over 200.

Fore Coot, with classical/organ music, and OHM 5000s, 250-500 juicy watts from a good Class D amp or appropriately beefy Class A/B may well add value.

My Bel Cantos I use on OHM 5s are 500w/ch of good Class D. That should do it I would think, but extra power in reserve if needed can probably not hurt, though some caution to avoid overdriving might be in order in that my 500w/ch amps seem to never break a sweat and I have never tried anything even more powerful.

I'd do the amp right first and then determine if any need for subs. With organ music, they may or may not still add something of value if set up right, depending.

Coot - If you review my more recent posts, you will see that my Odyssey Audio HT3 amp (w/ cap upgrade), which is rated at 150 watts/channel @ 8 ohms, was audibly clipping **in the midrange**, especially on vocals. I do run my Walsh 2000s with powered subs, but the Odyssey was struggling with the midrange. IMHO, I would go with a beefier power amp before I added subs to a pair of 5000s. You will still get plenty of bass out of the Ohms, and if your room is large, and your present amp is clipping, you could damage the 5000s.
