What's a Triode configuration?

Judy426 Is it actually a deficency with the AR or just a compatabilty mismatch between componets and ICs? I have been pretty fortunate with my matching and get very nice sound but I have been careful as to what I had and how I've changed. Also I have a great counsouler to toss opinions off of too. Right now I was looking as to how I tell differences between a pentode design and/or Triode, are all the AR Pre Amps/line stages Triode or what design would they be? Wanting AR is my personal choice I have always loved them and they were always out of reach for me, it's my personal dream. Now if Sonic Frontiers or another Pre was a better choice I am open to it I'm not being closed minded by any means, when I make a consideration for a seperate amp it will be a Classe though, becuse that was the reference for my speakers and I am hearing the joy of that matching and from the power cord changes I've made, so there I'm being unflexable at this time but, a Pre Amp to match might not be the AR as I would like and I'll have to ask at the time of that impemding change still again. We all have dreams and at this time AR is my first choices.

Judy426, I do want to thank you for your opinion and your suggestions, I don't want to be close minded concerning my future choice so when I am in position to be doing so I hope that you will be available to offer me an opinion when I have selected an amp at that time. But still what makes a Triode configuration different from say a Pentode? and what are some basic considerations in matching a Solid State amp with a tube Pre Amp? I'm not clear as to how the impedance matching works? (I do understand impedeance on a more simple level though).

Jeffery, Thank you for that explaination that helped greatly and I think I understand better now. Yeah I know that the audio world has changed over the years and I'm holding on to some older goals, can't help that I've always loved AR, Levinson and Classe products (I'm an old SS fan) that's all. I have heard some very nice CJ line stages before and yes it was nice. as well as ARs mated with the before mentioned SS amps and they were simply georgous! Now a days I won't go back to shopping for new due to cost, so I do a ton of inquiry to help educate myself. My musical tastes are all over but centeralize mostly on softer rock, I could go back to an Aragon Amp again (that was a nice peice) mated with a Tubes Pre but I would like to concentrate on a Classe as that was Apogee's reference and maybe an earlier amp would have just a bit more bottom end extention as well again. Thanks to everyone your help has been greatly appreciated.
