Audio Research I/50

5G;'s, not bad.
Jadis jhas a  I50 as well, How about that.
2 I50's avalible
Jadis is a bit , well most likely alot more.
But if you have 5G's, you also have 8G's. 
My power tube of choice would be the EL34
Pity my Defy will not accept EL34's.
As I say, tube amp = tube amp\Power tube = power tube.
only miniscule differences twix dif labs and dif power tubes. 
Blind folded you might/might not tella   a  kt120 vs a  EL34.
I just like the EL34's longer running life, lower  price, sweeter midrange  vs my KT88's. 
The EL34 is and will be the best power tube.
I;'d go Cayin EL34 amps or LM EL34 amps, or Muzishare EL34 amps. 
Tube amp = tube amp. 
Its all in the craftmanship/quality that sets one apart from the other.
Soundwise, they are all about equal. 
Including Dynaco ST90, Allan Organ amps from decdes ago, =  both sound just (almost??)as good as the Jadis Defy, with Mundorf top line caps/Takman Metal resistors. 
ARC is not going to blow away either of the 3 chinese stars. 
Blind test, ,,no wait, even no blind test, you'd be shocked at how close the 3 chinese stars are to Jadis/ARC big guns.
Tube amp = tube amp\
Power tube = power tube.(but each brand does have different voicing, = I found the Gold Lion KT88's not same sound as the Svetlana KT88,,,but I'm thinking the best in this class are the EH KT88's, which is my next purchase)
Myth  buster here. and 
Out.

I am really happy to see this product. Moving back towards bang for the buck, made in USA without ridiculous bling. If I was looking to downsize or building a compact system, it would be this. 

I'm also really happy to see this product.   I've had a Audio Research vsi60 for years and have been looking to upgrade (with another Audio Research amp) for a bit.   The vsi75 isn't available in black and neither is the Gsi75 and the reference series is expensive.  

Does anyone have a idea about what sort of comparison there is between the Pass Labs INT25 and this new offering?

Wonder if auto bias…..hmmmm.
