Wayne, 19 posts deleted! Man it must have been a pretty heated or un-related material posted. Glad I missed it (have been away for a few days).

I have a MPX3 Slam that was purchased new in December 2007, and I'm enjoying it very much.

I have a Platinum Extreme with BG outputs and a stepped attenuator. This machine started life as a PPX3 6SN7, which I bought used from samgotit. I immediately had Mikhail upgrade it to a PPX3 Slam with attenuator and only had to wait a little for that. Later I had Mikhail upgrade it to its current status. I got a bit of the "it's ready" or "it will ship next week" from Mikhail, but eventually only had to wait 3 months for it.

I've opened it up and verified that everything I've paid for has been done and am satisfied with the build quality and more than satisfied with its sound quality. That being said, Mikhail's behavior in the last year or so means I won't be buying anything else from SP and, if the amp fails, I'll be looking for a local tech to fix it. I really like Mikhail, but his recent behavior is indefensible IMO.

Happy Camper, does it say which revision of the board your Extreme is? I have pictures of my Extreme Platinum that Mikhail currently has and the board layout is different. I'm curious how old yours is.

Here's a picture of mine:

Penger,

Sent PM.

Should anyone else want to know, the one in my post is a PPX3-Plus Rev. A

This was one of the first batch to come out as part of the pre-order in late Dec. 06.

Looks like he has a dedicated board for the extreme in your unit.

Don't know if there is a pro or con to the revisions. I assume he would change for the better.

Wish I had a balanced source, I'd get Markmaxx's balanced baby. I have been convinced by the Betas at the meet this last weekend that for dynamic cans, balanced has the best sound.

Thanks for checking!

ES-1

2x: 2C51, 5687, ECC-1 adapters
4x: 3D21A adapters

Was sent in for upgrades, no problems so far and good sound since Oct. 2008.

I have a PPX3 on its way. The previous owner didn't know if any upgrades had been performed but it shows at least the headphone socket upgrade to Neutriks.
I'll have to give it a close look when it gets here. If all goes well, it should make for a nice little office amp.

So, this is the extent of Singlepower amps left in the Head-Fi community? Only 17 units

 

[Happy Camper]

Just a thought. Make this a sticky with the other SP thread so it doesn't get buried.
