Audiophile grade passive impedance buffer


Preamp balanced output impedance at 20Hz measured by Stereophile as 6.9k ohms! No problem into 90k ohm balanced input impedance of old amp, but new amp inputs only 10k ohms balanced. If an audiophile grade passive impedance buffer exists on the market, I haven't seen it. Will I need to run single-ended and thereby abandon a fully-balanced setup? Or does one of my components simply need to go?

@invalid Fascinating, who knew? Not I. These seem to have balanced OUT, but no balanced IN. Versatile and reasonably priced. Thanks.

Al from space tech can build whatever you need, just give him a call or email, he usually answers in a few hours or less.

@hickamore I haven't used his Analog Bridge, but I've owned Dan's LS100 preamp  in the past and currently use his PH 9.0XT phono preamp. All quality equipment from a quality guy. If you have questions about how it might work for your application, call or email him; he's generally very accessible and willing to help.
