Was running EL34s with PrimaLuna Dialogue Premium HP Integrated and Revel Performa3 F206s. Sounded good but maybe a little flat. These speakers are reputed to require power. Was thinking maybe F206s not compatible with tube amplification. KT150s added the dynamics I was after. Highly recommended if you have power hungry speakers.

I recently upgraded from a Prima Luna Prologue HP which I loved the sound of with KT88's and upgraded to a Prima Luna dialogue hp and went to KT 120's and just upgraded to Kt150's they have started to open up and are giving a little more bass to this great amp.

I have a pair of Quicksilver Silver Mono 90's. When it came time recently to replace my KT88's, I checked with the manufacturer and decided to upgrade to these Tung Sol KT 150's. A great upgrade. Highly recommended

The tung sol kt 150's takes the PrimaLuna Dialogue HP Integrated with standard el 34's from great to spectacular! More articulate while remaining smooth and rich...but it's the bass where things really take off. Bass is deeper and tighter with the kt 150's. Sounds like I moved way upmarket with my speakers. A very worthwhile and instantly enjoyable investment.

I've had my PrimaLuna Dialogue HP Integrated for just over a year and decided to replace my EL34's with the KT150's. Best decision I've made next to buying my PrimaLuna. They changed everything. My Martin Logan Aerius speakers have never sounded so Powerful, detailed and soooo liquidly smooth. If you have PrimaLuna Dialogue HP mono or HP Integrated don't wait too replace your Power tubes, worth every dollar!!

I usually expect small tweaks from tube rolling. However, the replacing the stock KT88 primaluna tubes of Tung Sol KT150 in my Primaluna monos yielded a huge increase in top to bottom sonic performance in every way. Results were better than advertised by Kevin.

I have a Jolida 502A integrated amp and Merlin Excalibur speakers. Pursuant to the suggestion on Upscale's website, I contacted Jolida to see if the KT150s would work with their amplifier. I was told that there would be no problem with the 150s and that they in fact liked the 150s a great deal, although expensive compared to other tubes. I ordered a set of four, matched and cryogenically treated. Once I installed them, I noticed a great deal more bass. Not boomy, but clean tight bass and everything else seemed cleaner. It was just as Kevin had described. The amp also seems to play louder at lower volumes than it used to. Now the that the tubes are broken in, I am in audio nervana; soundstage has opened up, bass is really tight and lifelike and the highs are very clean. I have been ordering tubes from Kevin for several years and not once have I been disappointed. Thanks Kevin.

I bought four of these for my Audio Research VSi75. If I had to summarize my impressions in only one word it would be: POWER. After a while I tried putting the KT-120s back in and there just is no going back. What an amazing upgrade!
