Thanks ZM. Unfortunately my garage it too far away from the living room to listed to the system.

But I still take time to listen to the music!

As Iím finishing up this system, and getting the cabling sorted, how do I figure out what the input impedance of these amps are? How do you measure?

I guess rule of thumb is solid state is usually low and tube is usually high. Iím using a tubed based DAC and a tube based Pre so I think some improvements can be made to correct the imbalance with the cables.

Default These amps are SPECIAL!!!

My Mercedes project is still at the paint shop this weekend. I did some polishing on the grill and bumpers, but not as much fun when I canít put them right on the car.

So stopped and played with stereo stuff, more fun.

Brought out my Ekta Grande speakers and Transparent ďSuperĒ cables to give a listen, now that they are broken in and running great. The built in JBL LE8Tís sound pretty good. But missing the deeper base and highs of a good 3-way.

I am super excited on how these amps sound. I would say a pretty big jump up from the F5 turbo v3ís that I stole the power supplies from.

Iím not sure how much the extra voltage and capacitance weights in, but the punch and power is amazing.

Anyway, thanks Zen Mod for your design, boards, time, and hand holding!

Thanks, Zen Mod for this outstanding design and very informative thread. I believe in a single transistor doing all the work at the output, albeit the price you pay when it comes to the total power dissipation, no coupling caps in a signal path, and thick copper traces where it counts on a PCB. The trace thing doesn't bother me really that much because I double up everything with pure copper or silver ribbons anyway

I am planning to make one of these for my 4 ohms-flat Dynaudios, that I was able to drive nicely even with a 3W single-ended valve amps...
