I thought that it was already stated that Emotiva was working on monoblock tube amps in the 200W - 300W range? I would swear that I read that on a thread, maybe even this one.
Are you assuming?
I was told by 2 Emotiva people that they would definitely debut a mono-block at 300 wpc running KT-120s. I was also told they'd release it in late spring, give or take. Edit: I was told this about the 2nd week of November.
An important consideration with tube amps is said to be that they lose their sweetness in megawatt versions.........., as well as all the heat and tube replacement costs, when output tubes run in the area of $50 each.
I really wish you could hear my 350 watt Carvers. As sweet as a Chocolate Sundae. Heat? I've only got 2 more KT-120s than you do and they're only running at 100 millivolts. There is no more heat than my Jolidas that had 4 KT-120s outputing 140 wpc. $50 replacement costs? Keep in mind lot's of guys are running KT-150s at over $90 each.
Technical requirements for an Emotiva Valve/Tube amplifier: SET (not in parallel or push/pull) Triodes only 300B Class A Monoblock Possible hybrid, i.e. solid state power supply with a stiff rail voltage of 600v Auto-biasing No Negative Feedback Point-to-point Silver wiring XLR or single-ended Cardas or equivalent connections
I think you'll be in for a personal disappointment.
They won't be SET. Almost certain that they'll be push pull. No 300B. Fairly certain they'll run KT-120s and probably be KT-150 capable. Little or no class A, Class AB only. No auto bias. 20db feedback. Definitely no point to point, no silver wiring, and no Cardas connectors. Any of this on an Emotiva amp? Never. Thank God.
XLR and RCA has a very good chance. Would that be enough out of your list? It would work for me...
