KT 170

I have less than five hours on a quad of them. I’m thrilled. It’s like having a new system. More lower mids, bass, live music feel. Was using KT-88’s. Speakers are not efficient ones. Got an email from my Amp maker saying he’s now offing them, so no worries in trying. 

Cuss words of joy. To me the lower volumes is where the fuller sound comes out. Loud is loud. By by KT 88’s I have a new love. My wife gave me a perfunctory agreement but that’s suspect. But she stayed for a while asking to hear some of her favourites.

wsrrsw-It's always fun to have that experience with a new addition.
I'm disappointed I can't try them in my amp PL HP. I will contact them directly to get confirmation on what stickmon42 indicated.

Full stop... Have to send back AMP (Roders KWM-88 Integrated Amplifier) to get some changes made inside to use KT170's so as not to damage amp. Went back to 88’s and will dig out shipping box ASAP.

I have 16 KT-170's running safely in my pair of PL Dialogue HP's.  Its just a mater of raising the rear tubes up about 2 -3 inches.  It would be nice if PL made a nice audiophile grade adapter to do this, but $5 socket savers plugged in together does the trick nicely.  The side to side dimensions are just fine. Its the front to back dimensions where you have glass on glass touching.  I crammed them  at first to try them out against the 150's and the sound was everything I liked about the 150's but more so.  Better extension on both ends, better midrange.  I have a small mid bass bump in my setup at the moment and these helped alleviate it somewhat.   The rear KT-170's are raised 3" higher than the front ones and it gives plenty of room for heat dissipation, and they are well away from the front tubes, so no glass on glass.  The socket savers are $20 for 4 on amazon so you need 6 sets of 4 for 24 socket savers  at an additional cost of $120 for the 8 rear tubes.  BTW If anyone is interested in 16 low hour KT-150's (about 300 hrs in a Dialogue HP).  I'm selling them at half price and will include 2 spares I used in my headphone amp.   I have many dresser drawers full of tubes I am not using and need to clean house.

Interesting arrangement for the KT 170 to fit, Brad.

Must look quite dramatic with 2 amps in your setup. Bet it sounds great.
