KT150 to KT120..or KT120 to KT150

Hi Dave

I have had a KT150 amp on loan to compare with my KT120 amp. 
I prefer the KT120. There is just something about the KT150 I find too Hi-Fi sounding and cerebral.
I wouldn’t characterise the Kt120 as dry at all. I think it’s a blend of a EL34 and a good 6L6. 
It just sounds a bit warmer tonally to me than the KY150 which does all the Hi-Fi tricks very well. 
I’m sure it comes down more to implementation than the actual tube. 
I have to add that the KT120 takes hundreds of hours to settle in and I think that’s why people dismiss them to soon. 
All the best. 

Would love to know the amp designer. I have been saying the same thing but everyone seems to be on the KT150 bandwagon. 
Keep us posted if you give it a try. I think you are safe to swap them in your Jadis. Might just need rebiasing?

@daveyf  I listened to the Jadis DA88smkii compared to the i50. I much preferred the 88. The 88 was considerably more expensive too. It just has such a musical sound with massive amounts of density. The i50 sounded very clean and Hi-Fi. The i50 has better bass but lacked density and warmth if that makes sense?

 I would’ve bought the 88 if it wasn’t so damn expensive where I come from.
