Even though I've never listened to an Inspire SEP, I have one from another manufacturer. The difference between my Triode-strapped Inspire and the SEP is quite evident when running any mid to large Pentodes or Kink-Tetrodes. I allocate an important portion of those improvements to the Triode configuration, as the other manufacturer is no slouch. You guys may remember me ranting about the EL34 being probably the most capable of tapping all the potential of Pentodes strapped as Triodes given their internal structure. So, I'm not surprised you found switching EL34's to a Triode configuration made evident improvements. Now, I'm wondering if ... Last edited by Musica Amantem; 11-06-2017 at 03:09 PM. |

Anyone over here interested in a quad of Stromberg-Carlson labelled 7408s? Think they were made by GE. Not sure how I ended up with them, but have no use in either of my current amps.
Couldn't agree more on folks take on triode vs ultralinear. Both of my current amps (Cary SLI-80 & CJ Classic Sixty SE) sound best in triode. The Cary with GL KT88s and the CJ with GL KT77s are the best to my ears.

Hi Guys. Been away for awhile. New project has me against the wall till April.
Just wanted to comment on the 6AR6 discussion. I tried them in both 6AR6 and 6098 iterations. I thought they sounded quite terrible in my setup and gave them away. No question. To my ears they were the worst of any tube I'd tried in my Inspire SET(P) |

Have you heard from Dennis in the last few weeks? Is there still some kind of hangup with his chassis supplier? |

No more tube-rolling for me for a while, as my mesh plate turned out to be still alive! (go figure, it is back working flawlessly). I need to concentrate in getting the EITR and the Audiophile Optimizer, and setup the virtual stream server with JPlayer/Linn Kazoo/MinimServer and call it quits, finally. I'm curious to know if someone has had a chance to compare PSE vs SE Inspire amp designs, with the same tube types, and could comment on sound quality differences (other than SPL's). Since everything is relative, it would not matter whether the configuration (which has to be the same in both alternatives) is Pentode or Triode-strapped, as I'm sure differences, if real, would carry out to both configurations. Thanks! Last edited by Musica Amantem; 11-30-2017 at 09:09 AM. |

Recently as discussions here related to some tube options I came to the conclusion that my memory of past tube rolling experience was fading. Even to the point of not recollecting having tried combinations, much less what my impressions were. I have no intention of starting over but I did try to put on paper the options so that I can reference them in the future. Also, as I plan to will my Inspire Amps and Preamps to my kids, they could use a little guidance. Anyway see the attached if interested. It may be comprehensive, it may not. Keep in mind my efforts were objective and manufacturer's were left out completely.
