KT-120 tubes vs Gold Lion KT88's

I like the KT-88's in my CAD 120s. I am wondering if the bias changes much when running KT-120's? Do they run any hotter? I may give them a try. How much is a set of 8? Thanks.

No the kt-120s are a better stable tube then the kt-88 to bias in the cad-120 I have noticed. Plus you Bias them same as you would regular kt-88's. I set them though around 140 MA, and I got them for $450 USD all in at upscale. Plus they match them for free a added bonus. They do how ever put out a little more heat for sure. I have a solid tech ROS4 Reference stand which is a not inclosed. I have the cad 120s on the bottom and about 1.5 inches from the bottom X shelf of my SLP-98p. Though I have the feet of silence under it and adapters. which raises it 4.5 inches above the cad120, so i guess I can call it 6 inches clearance in the end. Though I do not have an actual shelf just the X cross beams for the feet of silence. So I call it an unclosed design though at the end of the day it dose get hot at the aluminium centre ring.

I have used both and feel the KT 120s are the more balanced from top to bottom. However both sets seem to be a bit dark. I was wondering if the original EH Kt88s would be an improvement.

My experience with the KT120 in my Rogue M180s was that the bass was too strong for my system. Compared to the Gold Lion KT88s that I had been running for years the KT120s were also not as clear or extended in the high frequencies, and had more grain. However, there seem to be a lot more people who have had positive experiences with them so I would certainly say that it all depends their synergy with your system and your particular tastes.

Forget the KT120s and jump on a set of KT150s (not literally as pesky glass shards can get in your soup)…simply more of the same gusto as the 120s, but (in my amp anyway) effortless clarity in a great sounding tube that also looks like a pickle, which supposedly helps tame microphonics…ever heard a microphonic pickle? No? I rest my case. Another often rested case regards the paranoia about excessive heater current draw which seems unfounded as no case of amp destruction from this has been reported anywhere…and I've been looking out for this…ever vigilant.
