I spent several hours listening to amps from late afternoon and well into the evening with my Altec Seville speakers. While I had my trepidations about the ability of 1.5 watts of tube power to drive speakers without having to turn the amp up to 100% volume. I am happy to report that I was able to achieve room filling sound in an open floor plan living area with the volume knobs set between 10 and 11 o'clock. Yes, this one goes to 11 quite nicely! I went for a simple set up as adviced to see what the amps could do. An iPad via a 3.5mm to RCAs streaming Tidal. I went from Shelby Lynn's Just A Little Loving to Bill Evans to a Tidal listener's 50 track list of amazing female vocalists to Joni Mitchell to The Beach Boys' Pet Sounds. Wow . . . just wow. So much amazing, beautiful sound. Warm, yet clean and clear. Often, it felt like I was in a recording session or listening to them perform at an intimate club. I have what is (IMHO) a nice line up of tube gear, ranging from the Schiit Freya+ tube pre with vintage 6SN7s, a Cary 300b, Scott 222 and McIntosh tube gear ranging from 1963-mid 1990s. These Alan Eaton amps stand toe to toe with all of these pieces. It is a modern day classic. I am not sure how they can put together such a high-quality pair of amps for this price point, but I am thankful that they do. Keep up the amazing work!
