Hi to all,
The Pinnacle OTL is amazing amplifier.
Even with only the Fostex-FE208EZ in back loud horn not connected yet the tweeters and the subs (active crossover / Tri-amp), the sound is very musically, big, detailed, authoritarian and 3-dimensionally.
Better performance than 6V6 single-ended and Wavac md-300b that I have.
To mine opinion, the Pinnacle OTL has his own league.
Connect him to an appropriate speaker / driver and you in musical heaven.
Thanks to Bruce.
