KT 150 impressions

I heard Prima Luna I prefer the El-34 too!

I’ve been using KT150’s since the first batch made it to the US shores ... Some 5 years or so ago?? They are linear, open, transparent, and effortless. They have a top end which is seemingly limitless and a punch that grips with deep taught bass. They are powerhouses that exude confident control.Their neutrality denies they’re glass bottles and their forte is bringing solid state levels of control into a vacuum tube without denying much of a tubes’ virtues ... realism, tangibility, and 3D soundstaging.

I too love the EL 34 tube... but this isn’t even a distant cousin... which at first had me second guessing my decision to choose them. But they are so balanced... and do so much well...that I’ve found other places in my audio chain to add “tubed richnes” up the line via Dac and Preamp that the overall “blend” is like my favorite stew on a cold winter night. They’re great tubes. 
 Good luck and happy Lissn’n.

I’ve been through nearly all the KT’s and still today, the best tube in that family has been the nos green label mil spec GE6550 in the white box, this was a honey of a tube, glass was twice as thick as any tube in that family, you could hear it when you flicked it with your finger nail it just made a dead thud, instead of a glass tinkle.

Far preferred the 150s to the 120s, but I used them in different integrated amps, so it's not an entirely fair comparison.  The KT150s were remarkable - clear, dynamic, grain free, transparent, etc.  

I've used 150s in a a couple of amps and I like 'em, but like 120s more for reasons I can't explain thus saving readers from suffering through another explanation. My current favorite little Dennis Had SEP amp seems to work best with Gold Lion KT77s which I CAN offer an explanation of: It sounds better with them.

KT150 any day over 120s.  It is a very linear tube but doesn't have the EL34 overall midrange but sounds quite nice. 

I think they are very linear. Basically you can't tell they are tubes.

I also feel the KT120 tubes have some kind of glare.  I heard a friends Prima Luna HP Integrated with the KT150 tubes, it sounded incredible.  Deep taut bass and fantastic mids and highs.
