Balanced or single ended phono stage?


I'm currently researching phono stages but may not have the opportunity to demo them at home. I've taken a look at the Parasound JC 3 and the Ayre P-5xe which both have balanced outputs. I've also read great feedback about the Manley Chinook and the Audio Research PH-6 which can be found used for similar pricing used but are single ended.

My question is whether the balanced option should tilt me in favor of one type vs. another. I'm not too familiar with how important it is to consider balanced outputs when it comes to phono stages.

Current system is running balanced currently with a McIntosh C220 tube preamp, MC 402 amplifier and Ayre C-5xeMP SACD player, all hooked up balanced. I'm most likely going with one of the VPI tables in the classic line but haven't decided yet. Any good advice as to whether a balanced phono stage should make or break the decision since all the stages I've mentioned have great reputations?

Some pretty basic reality:

1. There are many reasons for the quality of sound of a phono stage, differential design being one of many. Balanced might be beneficial, but many non-balanced phono stages beat balanced phono stages. This single factor certainly is not the most critical determinant.

I don't sell, make, or endorse any phono stage makers, I have absolutely no commercial or personal bias. I own both balanced and unbalanced phono stages.

2. Differential circuitry certainly does not eliminate cable influence.

* An inappropriate impedance will still be just as deleterious to the sound.

* A cable design that rings will still ring. And this sounds horrible, balanced or not.

* A cable with leading edge overshoot will still have it. And this too sounds horrible, balanced or not.

* A cable with changing impedance relative to frequency will still have phase distortion, balanced or not.

* A cable that rounds transients will still round those transients, balanced or not.

Balanced design does not change any of the above at all.

Years of interface design experience in high tech, outside of audio, is my background for this statement. In the audio field technical testing and listening confirm this.
I think your "preamble" is not "really necessary", as you state, to give my response context.

My assertions stand on their own, balanced is not a sonic guarantee of anything. Neither is it a detriment. Maybe it will be quieter in your system.

As for noise, not all is cancelled out. We often will see a circuit with additional parts. Not perfection! I have no horse in the race but I don't like "black and white" statements, high end audio is too full of them, and most of them are wrong. And if you have ground loops, balanced dies not kill those.

To get back to your original question, "My question is whether the balanced option should tilt me in favor of one type vs. another", don't let this one feature tilt your decision. I never heard it be the make or break for any phono stage, and I have tested a lot of them, including many of those reviewed as the best, and own a lot of them.

Listen to everything you can get your hands on, don't pre-judge or limit your field based on things like balanced or not, use of signal transformers or not, specifications, circuit design features claimed by the manufacturer, or reviews. Go to lots of concerts without PA systems, listen to solo instruments whenever you can, and try to match that feel.

Again, no connection to retail sales or electronics of any type. Just a guy who hates the hype in this industry. It's about the music. Don't get lost in the technical claims.
I should have said, in the above post, "To get back to the poster's original question", not "Your original question".
