Aesthetix vs. Allnic vs. ARC ph7

The 0.22uF caps are coupling caps and the 2.0uF are output caps. In the signature series, the output caps went from 2.0uF to 4.0uF so they are a load to fit in. I have 4 per side to deal with in the IO and not much room.

I've been curious on how the Vcap coppers compare to the Duelunds. At somepoint, I may replace the 1st stage coupling to the coppers to find out. It had a teflon cap in that position to begin with.

Thanks Al
My BMC phonostage is indeed connected to the unbalanced aux input of the pre.

Good point, Al.
Just found this info from the S'phile review of the Rhea:
"The preamp's output impedance was a low 110 ohms at 1kHz from the balanced jacks, this rising inconsequentially to 156 ohms at 20kHz but, more significantly, to 3846 ohms at 20Hz. This rise at low frequencies is due to the limited size of the coupling capacitors and implies that the Rhea must be used with a line stage having an input impedance of at least 30k ohms if the bass is not to sound lightweight. The output impedance from the unbalanced RCA jacks was a high 2k ohms across most of the audioband, but as this rose a relatively small amount at 20Hz, to 3.05k ohms, the preamp's tonal balance will be less affected by the line stage having a lowish input impedance."

So to those who own the Signature version, there is a logical reason why it would have a superior bass response compared to the standard Rhea. This is an easy upgrade, however. The Sig version should drive 10K ohms ok though.

Sbrown, It's a matter of semantics. "Output" capacitors can be said to be performing a coupling function, since they are in series with the linestage input (on a phono only stage).
