Happy Birthday!

Tried & True says that their finishes are OK outdoors so long as they are not actually outdoors - that is, so long as they don't get rained on and stay wet. It may also turn out that the beeswax in the original finish would block the spar varnish from being applied. But ipe is really weather resistant - the worst case is that if the finish does not weather well, you have to sand it down in a few years and redo it.

I know people who refuse to use it, particularly in jointers and planers, because of the required blade sharpenings. But it is very durable for outdoor stuff. It might be prudent to add some spar varnish over the tried and true.

You can countersink 2mm thick panels, but you often need to use undercut screws.

Happy Birthday!

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

The above should eventually lead to this, which is delightful ... listen past 0:40 actually good ...

I suspect this will be popular soon

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?

Hastens.

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.
