I recently decided to purchase a factory built pair of ANK Interstage Parallel Single Ended Monoblocks. I just wanted to share how much I'm enjoying these wonderful, musical, organic, and surprisingly 'powerful' dead quiet amplifiers! Doesn't sound like only 20 WPC. In fact I'm finding it difficult to go back to my 5X as expensive very highly regarded KT88 based amplifier... Any others with experience with these amplifiers? Perhaps I'm just taken with their SET sound which I haven't heard in 15 years. Happy Holidays to all!
