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

Help me decide which amp for my 5000s.
Currently 23yr-old B&K EX442, ~190wpc. John S. says I may need more power.
I'm interested in either W4S ST-1000 or VanAlstine 600R.
What I'm after is lower, fuller bass and less midrange congestion. Open to other suggestions, not to exceed $4k.

Coot,

The w4sound is one i considered and simi!ar to bc ref 1000m amps i ended up splurging for. A match made in heaven, especially with a tube preamp.

John often recommends NAD amps whicb i like as well.

I recommend 250w/ch min, high current, and damping factor of 40 or higher with the large ohms. My f5s that i settled on the Bel Cantos for use the similar size walsh 5 driver that came prior to the 5000.

I was considering the NAD M2 but I'm a separates kind of guy.

Mapman,
Did you do a critical comparison between the BC's and the W4S? What was it that influenced your decision to pay the xtra?

Coot, just curious but have you tried your B&K on the 5000's yet? You might see how it goes before spending the money, you might be surprised. Or not......I do like the Bel Canto amps myself though. Enjoy the 5000's! Tim
