Not sure if it's appropriate for me to chime in here, but here goes. As I said in my review, you really don't need to worry about burning your fingers on the tubes. I am 6 foot 6 with big hands. It's not an issue.
With regard to the Decware amp mentioned earlier in the thread, that amp seems much more versatile. You can roll all sorts of tubes including the 6L6, which I generally prefer to the EL34. And you can ask for more than one input, but at an additional cost. If you need more than one input and if you like the idea of rolling 6L6s, KT88s, etc, then go with the Decware. I haven't heard that particular Decware but I did own the little 2 watt one (the Zen?) with those Russian radio tubes / EL84 compatible. I found it to be very fast and almost too airy. I sold it after a few weeks. I was much more impressed with the Decware CSP2+ preamp/head amp, which is probably one of the very best head amps in the world. I regret selling that one. I don't think Decware has a bad product in its line. It's a class act.
Having said that, another issue to consider: the Decware look. To me it's a bit DIY. The Coincident wins on that score. Also, everything from the power cord to the RCA interconnects to the speaker wires connects on the top plate of Decware amps. It can present logistical and aesthetic problems.
But I am certainly tempted by the Decware! Lots of nice 6922s out there to be had at a reasonable price.
As for the Coincident Dynamo, I love it. I bought the review sample and frankly I am listening to music once again upstairs in my living room, where the amp rests on top of an armoire. It has replaced a $400 (including shipping charges etc) Musical Paradise MP-301 mk3. The Coincident is easily twice as good.
As for selling a Primaluna Prologue or Dialogue... well, I've done that twice to feed the habit but in retrospect those were bad choices. Primaluna is built like a tank and with the KT120 tube it is twice as good as with EL34. I sold my Primaluna to fund the purchase of a Line Magnetic amp. But that's another story!
cheers, tim
