While I'd love to hear the SIT amps it looks like you need to spend a lot of money ($10K for monoblocks plus additional for single stage DHT preamp)to essentially approximate what a good SET already gives you for a lot less. On top of that, you will also be stuck with a sonic signature that you can't change. If I want to alter the sound in any of my tube amps I can simply change brand of tubes. Will keep an open ear on the subject but have been disappointed in my ventures into the land of high end SS amps. I really want to hear a SS amp that I can love - at least for the summer months so I can avoid using my tube space heaters.
