Amp suggestions for Audio Research LS-16

The D-115 runs very hot. I have the metal cover off to help dissapate the heat which helps keep the tubes cooler. I can't say how frequently the tubes need to be changed because I have only had the amp about 4 months. When shipped to me 2 of the output and 1 regulator tube broke (Gold Aero). I replaced with Svetlana 6550's at just South of 200.00 (from Triode Electonics 6 month warranty on tubes). I expect based on my conversations with other owners that tube life is about 2000-2500 hours maybe more if you keep the amp in a very well ventilated location and KEEP THE COVER OFF! Good luck.

Thanks for all your help. I came across a Plinius SA100 MkIII and decided to give it a try. Should be a good combination.

Let me know how the Plinus works for you.

Try the Discovery Signature balanced cables for your system. They are most neutral and musical.

Abruce- The Plinius SA100 MKIII sounds incredible. I was listening to Vivaldi's Four Seasons and never notice the harpsichord before. Also on Clapton's Unplugged he uses a mandolin on one of the tracks that I never noticed before. Great amp! Seems to work very well with the Audio Research LS16 and Audio Research CD2.
