I doubt they could relocate the tubes as there wouldn't be any way to open up the player with the tubes on top. Some internal structure could be made but I just don't get the point. The 6H30 is good but the ECC99 is a better tube in many regards.

The DACT is the only choice at it's price level though you could maybe buy a switch and do it cheaper but it's so much more work. The next step is P&G then there is the RK50 and a Shalco fitted with some esoteric resistors like Riken or AN Tantalum.

You are both nuts...

I would call him reckless as he put the fate of his company in the hands of fragile electronics with no backup. All electronic components will fail and it is pretty irresponsible to assume otherwise even if it was for only a short while during upgrades.

Ahhh, so you've received it. Congrats! These small Stax amps are perfect for office rigs.

I think the upgrade was something like 1200$ over the stepped attenuators but I'm not sure. They can be found for about 900? and the 2 deck units for 400?. It sounds cleaner then anything I've ever heard. The RK27 is very grainy and colored by comparison and so are the DACT steppers. For me it's mostly that I can't deal with the steps as there is never the right volume level and that gets old really fast. Yes, they are Black Gates WKZ caps. If you have to use electrolytics then they are on the short list of candidates.

The electrets work with any Stax amp or adaptor, 5 or 6 pin. Just be careful with the volume as excessive level aren't good for them.

Nope but I have borrowed one from a friend to try out. Massive beasts. It's the same that Headroom uses in their amps if you don't want the steppers (and pay the premium)

Hehe didn't see your post. Funny that we both used the same picture as I had to dig around on my server to find it. + Those are my very beautiful NOS Sigma Pro's. My first Gamma Pro's were mailed to me today... The RK50 cost around 1000 Euro's but it's worth it.

The SET wasn't supposed to be there. My bad! The input stage is single ended and all triode but it could use some work.

I think this one is since 2005, back when life was a whole lot simpler. Justin...

The pictures are in the HF photo gallery. I'll try to find one and upload it here.

An OTL amp will always sound better then running through one or even two transformers and for most amps you can use something like the Mundorf Silver-Oil caps with their 900vAC rating and they are very good caps indeed. I've always been meaning to buy some Chinese kit amp and fit it with a Stax output and some other features. I have one in mind but time is always a problem and so this remains untested in the long term. A simple switch on the front panel that would disconnect both legs of the output transformers while the Stax socket is active should create a good all rounder as you would have a p-p DHT SET for some speaker use.

Producing a split L&R level control with the ELMA switches isn't possible AFAIK but it could be possible with some other switches. Shalco maybe? The KGBH sure is pretty but it really needs a quad RK50 pot...

We need pics! These have to be stellar headphones when you can get the SR-007A for 1650$ shipped in January.

There is only one plus to the separate L and R volume controls and that is balance control. Steppers are shit at that anyways so just give me a quad pot and I'll be happy.

I really do like my silver BH. Understated and functional but then again I'm a devote follower of the simple copper chassis approach.

The 845 needs more then 900v to start to sound good so 1kv would be the target.

You need output caps to eliminate all DC off the stators and resistors to restrict the current flow.

I might. I really like to hear what the SR-007 sounds like with some really big tubes pushing them.

I would go out and try some nice, revealing cables. They do not have to be silver as they could be gold, copper, amorphous metal but aim for small conductors and good connectors. No fancy RF! canceling geometry as a straight wire works best. This mirrors my findings completely. Putting a He90 in a SR-007 matched system will only end badly and vice versa. The He60 comes closer to bridge the gap along with the SR-Omega.

I was watching it before I logged onto head-case yesterday. I've been doing this for far too long to miss something like this... As it turns out the seller is a Stax fan as is saving up for some Omegas. I was only too happy to help.

This could be turned into a Stax amp as well. Could be pretty nice indeed

40 is for amateurs...

Nahh, we're too busy bashing the noobs
