Power amp for Silverline Sonata III

This is an interesting suggestion.
Have heard a bit of the "lore" that surrounds these amps, there is a bit of that with the older McIntosh things as well.

Not a lot of CJs on the ground here in Australia. VERY few!
IF they are switchable at the transformer to 240v/50Hz I would look at grabbing one of these if a seller was interested in going to the trouble for an "exotic" buyer....

The 240v/50Hz switch is not something I can comment on but the lack of availability [of the CJ's] down there is a shame...I think I added a few too many model #'s when I listed the CJ's, the ones I'm certain about are the old style conventional chassis models which definetly include the MV-45 and MV-50. Soon after that they changed the chassis (and continued upgrading the model I'm sure) on a different chassis style/platform. The MV-52 was either the old or new style (I'm still thinking old?) but I think the MV-55 began the new chassis and later changed up to an SE model(s) including an MV-60. Sorry to throw all these at you but I'm sure their website will probably clear up any questions. I'm not familiar with your preamp, is it SS or tube? Isn't Plinius fairly close to your neck of the woods? (New Zealand and a good reputation for solid state? -though I know we're preferring tubes...).

Thanks.
I had a look at the CJ site and the MV55 is still the "old-style" chassis, the last of those before the angled "buttress" style I think ??

I was actually in "Plinius town" last month :) I worked for the company that introduced Plinius to Australia....waaaay back when (early 80s)......a lot different range now though.

The Supratek pre's well known around here, they are tube pieces made in Western Australia. Mine emerges off the waiting list this week I'm told.

As for power amps, I think I've got the short list down to Quicksilver V4 or Atma-sphere M60 MkII. The OTL thing intrigues me, looks the way to go.
The multi-voicing I can do with the V4 is compelling though.

The OTL thing intrigues me too. I've heard the Atma-spheres briefly at the NY CES a couple of years ago but not with any other equipment I was familiar with. It seems the M60 MkII is the bread and butter of the line with extensive accolades. There is the S30 also, just for the record... I would love to hear the Sonatas with the M60's... I've read they're not the absolute best in bass slam, as compared to hearty SS but their clarity and speed are beguiling. The V4's would probably be deemed more traditional and the OTL's more exotic but again, the Sonata's inherent flexibility gives you these options like very few other speakers can. "On paper" so to speak you could make arguments for or against either camp but there's no doubt the true convincer would be an audition of each with your equipment... in an ideal world, so it would be. As is so often done, you can use price as a deciding factor to begin with... enjoy whatever you buy for a while (I'd estimate the V4's to likely be cheaper?) and just keep the others in mind for "down the road sometime" and possibly arrange an audition with them if the opportunity ever presents itself. Good luck.

Thanks Lissnr (and other contributors)

Being on the other side of the world from where it is all happening makes it hard to try all the possibilities, so I just have to "wing it" with as much good input as I can get, and working from a lot of experience too I guess.

In the meantime, the Sonatas sound superb with my zero-feedback SS amp, and I can't wait to get the amplification they deserve.
