Default Your Opinion on Tube Amp Reliability???

There are some integrateds in all price ranges by C-J, Audio Research,
VTL, Manley, VAC if you have the bucks. Next level is varios amps made
in China and then upgraded with the latest high end parts. I emailed you
a website in Western NY that specializes in those around 1-1.5K for 50wpc.
There are some issues surrounding the depth of soundstage in your room
versus the proper amount of power, but other members are more qualified
than I to discuss the right amount. There are integrated amps that go up
to 85wpc. If you need more, then a preamp/amp setup is required like
Bruce has.


Just for the record, my preamp/amplifier combination has approximately 70-75
watts/channel. The C-J Premier 11A is rated at 70 watts/channel into 4 or 8
ohms with its supplied 6550 output tubes. However, I'm using Ei KT-90 Type 3s
which, according to several tube experts, produce slightly more power in most
amplifiers suitable for their use. Before switching to KT-90s, I checked with
C-J and was assured this was an appropriate "tweak".

I am probably going to get into trouble for saying this , but the higher
end tube amps sound the same as solid state. We are going to need more


information about what you intend

to drive in what size room.



My room in 20 x 14, with an 8' ceiling.


Could you live with an integrated amp or do you want to go bananas with
dual mono amplifiers.



I think an integrated amp will do me fine. I don't ever "turn it up". I
have Spendor SP 1/2
speakers on Sound Anchor stands. Kimber 8TC cable, various interconnects.


As far as sending amps back to the manufacturer is concerned, I think
that is a good idea if you do need repairs
but it is a rare occurence. What dealers do you have nearby or within 90
miles? Would you be buying a new Conrad Johnson
or a used one?



I have no dealer within 200 miles, so I will be buying over the Internet.
