Audio Research I/50

Thanks to both. I'm looking long-term for a small, quality tube amp for my new Klipsch. I'm sure either of these would fit-the-bill. I'd lean toward the BAT (is the ARC triode?). Also, I've always wanted the legendary 300B in my system. Currently I'm "House rich" (small "r") so I don't have to worry about it for a while. I remember when $9000 used to be a lot of money.

I’ve no idea, but the $9K referenced in the ARC link I posted is from an Australian site, and maybe therefore AUD? If so, AU$9K ~ US $6600. Guess we’ll know more eventually. 

 I'm breaking in the Klipsch Forte 4 in my Home Theater system and they sound great! Planning to try them in my music rig shortly. Have a feeling they are going to blow me away! And with 300B or Triodes? Wow.

I see now the Aussie link I posted above has been disabled - odd. 
Hopefully ok to link to other audio forums - found this brief discussion: https://www.audioaficionado.org/showthread.php?t=49413
