Best amp/preamp combo for Wilson Watt puppy 5.1

Muralman1, you are not even remotly related to H2o, are you? By the way,aren't they more like Aleph series?
P.S. So far even their site under construction, then how about waranty?:)

Dvavc, Related to H2O? well, yes, I am at least three quarters water. :)

Oh, the amp. No, not at all. The builder lives three thousand miles away, and
sells direct.

No, H2Os aren't anything like an Aleph. Far from it. In fact, I can't think of an
amp that it reminds me of. The H2O is music, with all the dynamics, all the
layers, all the liquidness, and all the extension of the real world. Read the
review.

An amp with high power and current is ideal. While the Wilsons are highly sensitive, their impedance curves can be tricky, and are rated at a nominal 4 Ohms. The person from whom I purchased my 3/2s (which were upgraded by Wilson to bring in spec with the 5s) drove them with Levinson 434s, fed by the 390S CDP / preamp. That seemed to be a pretty good match.

Sdatch, do you know what is the impedance of the midrange drive in Watt/pupys? I got to change a midrange drive, and I know Wilson uses Skan Speak 8545 drive. I ordered one from Madisound because they sell it for $145 a 1/2 Wilson's price(of course Wilson claims that they modified drive, but I didn't believe them). Now you just confused me with that impedance because Scan Speak 8545 rated at 8ohms and I'm thinking that may be they indeed modify that drive.

Dvavc - Wilson doesn't modify the Scans ... they are build to their specs at SS factory, in Videabek, Danemark.

Having been in Scan Speak factory and having spoken with their head engineer - Mr. Lars Goller - I can tell you that most of the manufacturers order the drive units to their specs, so chances that Wilson uses the standard 8545 are minimal. 4 Ohms voice coil is only one of many mods you can order. Wilson probably also orders a shorter voice coil for higher sensivity too.

I have had a pair of 8545 mid woofers made by Lars for my car - they were 91dB and 4 Ohm.
