Description

I wanted to build a tube system around the highly sensitive Focus HD's, which present a very stable 4 ohm load. With the NEO250's optimized for a 5 ohm load, I thought it would be a good match. The HD's havent hit the 300 hour mark yet, so the transformation hasnt started yet. The amps currently have less than 50 hours on them as well. However they are starting to mesh well. Thinking about upgrading into the new Fosgate Signature tube phono stage, which is dual mono. Some tweeks here and there left, such as room treatments, that should keep me busy for awhile.Oh, and chasing those ground loops...

The Manleys will drive pretty much anything. I run Thiel CS2.4 speakers which are 4 Ohms and significantly less sensitive than the Focus HD. The Thiels NEED a good amount of power to come alive and that they do with the 250wpc Manleys - or 100wpc in Triode mode.

I recently retubed mine with the more robust 6CA7 tubes. 10 6CA7 per monoblock. Ouch!
