Default Intergrated solutions?

Hello!

I am almost done with my LM3875 from Mr. Daniels and have some questions regarding the final stages.

I have a B1 practically finished, and also i have a SKA volume buffer aswell. I am thinking about cutting my chassis expenses down a bit and going intergrated. What do you reckon would be the best solution?

An extra powersupply and the tiny SKA vBuffer, or just a simple non-buffered pot, say Blue Velvet? I like the idead of a buffer, and I can roll the opamps on it too. Intruiges me.

Also, if buffer, how do I hook up both power supply's to one PEM?

Do I use those white sugarcubes to run wires from the PEM and then to both PSU's, sort of?

Any one tried the Goldpoint rotaries? They seem easy enough to hookup, even for me

Any feedback are greatly appreciated, aswell as much neededd, thank you all!

I used an AMB e27 board to mount a 25k alps blue velvet inside my dual mono lm4780 build. It is silent throughout the entire range of operation. I am pretty happy with it and it is much cheaper than the goldpoint!

I have looked at that board, very nice. I am just sort afraid to run into any impedance mismatching, later on when I am done with my dac and phono box.

Certainly cheaper than many options, and definately more easy than the sigma 24 & 25 to power the SKA Vbuffer...

Thanks..

Any other thoughts, anyone?

This one is a very good choice if cost is an issue and it has the spec you need. I am using it naked to control a dual MyRef FE build.
