Aesthetix RCA Phase output question


Hi,
I have question regarding my Aesthetix Io sig phono stage
output, I would like to try RCA instead balance connection to my preamp (ARC Ref2 mkII) but there is
two connections per each channel phase + and phase -,
can I use + on each channel output ?
I use VPI HR-X (JMW 12.6) and VDH Colibri XCP (HO)
Best Regards and thanks for input

The Aesthetix Io is true balanced design from front to rear, including four deck balanced volume controls (if so equipped).

When you look at the rear you have choice of true balanced (XLR) or RCA as phase normal (+) or phase reverse (-). Your Audio Research is phase correct, so the plus (+) RCA jacks are the correct ones to use.

thanks Albert,
Recently I have read in Absolute Sound that Io sounds much better in single ended mode both in and out, what is your experienced, in my system rca in and xlr out sounds better than all rca. Rest of my system Tenor Wp75 balance connected to the ref 2 & Amati Homage

I like the Aesthetix both ways. Single ended has a bit more "magic," sort of a SET kind of sound. The balanced is more dynamic and streamlined and slightly better noise and control.

Since my Soundlabs are already fairly musical and lack the punch of dynamic woofers, I am currently running Purist Audio's cable for the Japan market in balanced mode.

I still occasionally recall the magic of Allison Krauss when I was all single ended Dominus. It was not as wide band or as dynamic but the soul of the music would put chills all over your body. Especially if your attracted to Alison's voice and fragile beauty as much as I am.

My most recent upgrade was rewiring my Walker turntable, using XLR connectors obtained from Jim White at Aesthetix. Although this is not balanced in the true sense, the Aesthetix connectors are superb and combined with the new Ferox Purist Audio cables, it is an incredible combo.

The transfer of my .25 MV Koetsu output to Io actually went up in volume approximately 1.5 DB. This is an indication of the ability of this new wire to transfer very delicate and low intensity signal over a 1.52 meter run.

One last thing. The review you mention was performed with all stock Russian tubes, so the added "beauty" of single ended was almost a requirement to add a bit of musicality to the system they used. Balanced with proper NOS tubes is more musical than single ended with Russian tubes and the benefits of balanced remain.

Of course you could go with NOS and stay single ended with Dominus and have 24 hour goose bumps. In other words, everything is relative to the gear and situation and what the listener prefers.
