Description

There is nothing off the shelf in this system. Every item has been hand selected tuned and tweaked with one purpose in mind; Producing the best sound reproduction possible. The dedicated listening room has isolated walls. A custom step down isolation transformer powers the system. Custom room treatments absorb and diffuse sound. The speakers are actively and passively bi-amped with a single ended amp on the horn and a push pull amp for the bass. The speakers are time aligned after the x-over and amplifiers. Improvements over the years are very slow as I long passed the point of diminishing returns.

Awesome system that I've been fortunate to hear. The fact that's it's all DIY makes it that much better...

Thanks for the comments.  

The preamp is not a kit just some OCD handiwork I put together.  

The interstage in the Push-Pull amp is truly the way to go for splitting phase.  The sound is truly effortless.

Nice system.  I've heard it and it is very good.  It will be magical in a larger room, IMO.

Nice. Also nice touch building your Push Pull amp with interstage transformer splitting the the signal. I am guessing your sound is very tactile dynamic and immediate. Regards Jet
