I had initially changed out an Aestheix Atlas amp for a pair of CJ LP275M mono's. Each amp has eight of the ST120 power tubs and three 6922s. I felt they made my big Wilson Alexias soubd even better (deeper extension, more soundstage). I had thought of going with Atlas mono's but once I locked on to the big CJ's there was no going back. After that I got a chance to try a CJ GAT S1 preamp and it fit wonderfully in between the be mono's. As good as the Callisto sounded, the GAT was right there with it and took up less space and has a lot fewer tubes. The Callisto was the Eclipse level with sperate power supply and separate remote control box. If I remember correctly, there were at least seventeen tubes total. Again, it was a great preamp, just the GAT was its equal, but in an easier to live with form factor, Then, I replaced the Rhea phono stage with my CJ TEA1 S3. The Rhea was the Signature level and before selling the Callisto, I had considered having it upgraded to Eclipse level. However, I came across the TEA and after demoing it, I was convinced it was an upgrade from the RHEA and it gave me the opportunity to have a complete CJ system. Please don't get me wrong, I have the utmost admiration for Aesthetix. Build quality and sound is first rate. I'm just happier living with my CJ system.
