Does anyone have a few Analog MAT03's or SSM2220's around they would like to share?
-
The tax deduction for donating them will cover the cost to send them to a ripping service.

My first vote would be to chuck them all. I did, when we moved, and I have not missed them at all. You can probably get a decent tax deduction if you donate them. My second vote would be to find a local cabinet maker, and to get him or her to make something for you.

Happy Tuesday in May! It's good to see you around.

Happy Birthday!

It didn't work out for me, but Tom will be there with some new stuff.

Same with the HD800 Ss

I still have a couple of prototype amplifiers available. One is a Black Diamond with an upgraded power supply ($1100). The other is a DSHA2 ($1200). Both amps use transformers for gain. More information at http://ecpaudio.com/stuff.shtml, or send me a PM.

Very sorry to hear. Such a handsome boy.

I saw Xanadu in the theater when I was 6. And owned the soundtrack.

Maybe I missed this earlier - what are the drivers? And is it basically a 25 liter sealed box?

The Copenhagen is a differential cascode circuit. The Copenhagen V uses tubes (valves) for the upper device, while the Copenhagen S uses transistors (sand). They are otherwise just about the same. It does indeed use input and output transformers (amorphous Lundahls in both cases, though the inputs can use mu metal instead). The tubes (E81L's) need not be matched at all. It is what is often called a "transconductance amp". In essence, it uses the headphone's impedance as an I/V converter, and it takes advantage of the slight Sennheiser impedance bump to make it a bit more euphonic. When used with Senns, I'd describe the sound as happy and punchy (kind of making them sound like how Grados would sound if they were not grating) - some people hate it, others love it, but it definitely has a sound. It can be linearized with the addition of some parallel resistance on the output (this is what a triode amp does except the parallel load is the tube plate impedance). Without doing that, it is not great with the Focals. Even with, they are so poorly damped that it would not be my first choice for powering them. With phones that have a flat impedance, it is pretty neutral. It's not an amp for everyone (definitely not for the objectivist crowd), but it is my favorite these days - I use a Copenhagen S with 650's for most pleasure listening.

You could make it slightly more complicated with the help of a laser turntable.

That is a "Copenhagen V" headphone amplifier. Power supply is external.

We did end up buying the hand made, foam and latex free bed. It was over the top, but, after daily back pain for years, to suddenly realize my back has not hurt since the day we got it has made the price worth it.

Speakers look great, but I'll never understand the desire of woodworkers to hand make things out of natural materials only to coat them in plastic.
