OTL amps with Wilson Watt/Puppy 6s

From everything I've read about OTL's, mating them with a low impedance load like the WATT/Puppy is a no no. I personally wouldn't do it. My WATTS go to LESS than 2 ohms in the critical midrange, even though they are a nominal 4 ohm speaker. You'll get some thin sounding speakers IMHO. They also have some very wild impedance swings with frequency, they are a tough load to follow. OTL's like high impedance speakers. I suggest the Coincident line (10-14 ohm load) as a better match with OTL's, if that is what gets your heart a-pumpin'. Good luck.

Rlennan: Which version WATTs do you have?

I have heard the Wilson Watt Puppy 6's with Atma-sphere MA1 MKII.2's, MA2 MKII.2's and the Tenor 75 Wi. They all played beautifully. You can clip the lower power OTL amps at over 100db with the WP 6's, but it really takes an awful lot to do so. I would not sacrifice the transparency, extension and purity of an OTL for any other type of amplifier.

An important question I would ask is what size is your room and how loud do you listen?

I certainly favor the Tenor's by a wide margin, but since I handle the product, that should be considered. :)

Good Luck!

Yes OTLs like high impendance load but thanks to the Zeros, I am driving a pair of Vandersteen 4A full range (5-way, 4 ohms nominal, with double 12 inch sub woofers) with a pair of Atma-Sphere M60 MkII monos. See this link for info about the Zeros. http://www.condor-connection.org/asog/tweaks/ps/zero/index.html
Call Paul Speltz up and he will help you. Also see the numerous postings on the Zeros on ASOG (http://www.condor-connection.org/asog/bbs/index.html) and Audio Asylum (www.audioasylum.com) sites.
Good Luck

I read somewhere that Wilsons' N.American sales mngr uses the Atma-Sphere OTL's on his personal pair of MAXX's.
I think it was the 140ish watt monos, so not even the biggest of the OTL's.
I've heard WP6's with a variety of amps, including a Linn Classik @ 75 tiny ss watts into 4 ohms, it sounded quite lovely.
YMMV

i spent 2 weeks with the Atmasphere MA2 mkII.2 and 1 week with the Tenor 75Wi with my previous speakers, the Watt/Puppy 6. both were excellent......easily the best 2 amps i have ever heard.

the Atmasphere was perfectly matched with the power hungry WP6.....plenty of power, no dynamic limitations i could perceive, excellent extension and resolution, with ease and purity. in fact, i was ready to buy the Atmasphere........

then i heard the Tenor. not as perfectly matched to the WP6, good dynamics within it's performance envelope, but at higher than normal volume levels it could get hard on peaks or go into soft clipping. no problem at normal listening levels. but the Tenor was more extended and articulate in the bass, had better clarity and refinement, and was faster than the Atmasphere.

i bought the Tenor, but also got different speakers. my recommendation for WP6 speakers would be either the Tenor or the Atmasphere, depending on listening priorities, size of room, and musical choices. you will love either of these great amps. OTL is the only way to go IMHO.
