They do have balanced outputs - don't let the RCA connectors fool you. And you can feed those balanced outputs into a balanced phono preamplifier - some of which also use RCA connectors on the input.OK, you will have to explain this one to me. Many turntable manufacturers offer DIN outputs but you are obviously saying that those that only offer RCA outputs (like VPI's for example) are actually balanced. IMHO, you won't find too many phono stages that offer balanced operation. Case in point is my Manley Steelhead. Right from Manley;
FAQ #1: The Steelhead is unbalanced. Why can't I have balanced outputs?Yes the Steelhead is entirely a single-ended design. The circuitry uses single-ended topology. In order to be able to provide balanced outputs we would have to convert the signal to balanced using something like some IC's or transformers. Both these options would add more "stuff" to the signal and be certainly audible detracting from the pure sound the Steelhead provides. If you are driving a balanced preamp or balanced amplifier with the Steelhead, check to see if you also have unbalanced inputs, change your cables and go with that. You might be pleasantly surprised that they too added extra audible "stuff" in order to provide balanced inputs and the RCAs that don't have that extra "stuff" in the signal path actually sound better. (Depends on a given unit's specific design.) Or use some RCA to XLR adaptors. Most balanced gear has no problem being driven single ended but check with the manufacturer if they are going to want the negative pin 3 of the XLR grounded or floating. Transformer-coupled XLR jacks always can be driven single-ended by running HOT into Pin 2 and grounding pin 3 to pin 1. Some IC coupled XLR inputs will want pin 3 floating, others will require it to be grounded when running single-ended into it. Check with the manufacturer of your gear to see how to hook it up single-ended.
