Anyone try KT150 in Primaluna Dialogue Premium HP

I love my HP. I've had it over a year and have rolled KT120 into it from the EL34. I like both sets. But the EL is more "liquid". The sound is awesome. With the KT120s I like the added power and punch. But it can be a bit fatiguing. It's the midrange glare that I notice most. So I wonder if anyone has rolled KT 150s into it. Does it keep most of the niceness of the EL 34s?  Do the 150s have less of that midrange glare?  

What at are your thoughts if you've tried this?  Maybe Kevin Deal has an opinion?

I do believe I've read of other people using kt150's in a hp and prima luna even lists the 150 in there tube selection.

George is spot on with the amperage figures and I think the hp would be able to handle the kt150 without any problems.

I don't own a hp but I have found the kt150 tube to be very good,giving the midrange qualities of the el34 and the drive and dynamics of the kt88 and kt120 but with no etch and glare.Most other amps that use the kt88 and or kt120 are'nt able to use the 150 unfortunately they don't have strong enough pwr Supplies.

Best of luck to you,

Kenny.

I recently replaced the old stock Mullard el34s in my amp with Genalex - Gold Lion KT77 and like them much more in all parameters. First time using anything other than el34s, highly recommended.

lalitk,

I have only used the new production tung sol kt 150,they are the only ones I'm aware of.I'm not sure if your vt-80 can use them.

Jetter,
The gold lion kt77 is just a wonderful tube I have used it in a couple of diff. amps with excellent sound.I have also recommended the gold lion kt77 to several people and they just love it,I have even heard them in a very nicely upgraded restored dynaco st-70.

I’m pretty sure the HP can use the KT150. Ask Upscale Audio as they are the importer. It is a very nice tube as I have some with my Premium (non-HP). Mine aren’t quite broken in but they have a nice midrange, good extension and great bass punch. From my understanding and I am not sure what speaker you have and their characteristics but a slightly warm IC would work very well with the 150’s.

I didn't care for the KT120 with my PL Premium and agree they had a nasty midrange glare and I couldn’t get rid of it no matter what driver or gain tube I used. Otherwise not a bad tube as other manufacturers have used them successfully.
