Thanks to all who have responded. I need to consult Victor K. at BAT to ask him about the XLR to RCA type cable, and probably reconfirm the use of the Rogue variable pre-out with a fully balanced amp. BTW, Mogami makes such a cable, and also a XLR to XLR cable, both sell for approx between $40-50.recommeded by one of the above members. I Have not checked out the Signal Cables recommended by another.
To Almarg and Hasmarto: The Mogami cable XLR(female) to RCA (male connectors) are all of one cable, not an "ADAPTOR" ADD ON to a XLR to XLR cable. The drawback according to Mogami is that you lose the benefit of reduced noise offered by XLR to XLR which somewhat defeats part of the purpose of using a fully balanced amp.
I understand, Hasmarto's claim that the Rogue Sphinx is not in the same league as the BAT VK-200. As noted the new Rogue RP-1 uses only RCA inputs and outputs, but the pre-amp should be superior to the pre-amp of the Sphinx v.1 or the upgraded Sphinx v.2.
Lastly, I have no intentions of keeping the Sphinx v.1. but also looking for pre-amp with possible both XLR and RCA connectors. I have a Ayre CX-7e mp CD player which is outstanding and has an XLR outputs which an a fully balanced cable should improve its performance
So as it stands, I just need to find a pre-amp with at least 3 XLR connectors: two obviously for the amp, and one for Ayre CD player. It would be nice to find such a unit with a remote control, and the bonus of of a good quality phono stage. I am not interested in a built in DAC, or HT processor or loops.
AL, thank for the tip about the Neutrik adapter: Also the headsup about ARC pre-amps not working with a XLR to RCA cables; I saw an ad on AG for a brand new ARC LS-17SE, but it has NO phono stage, (not sure about the remote) I am also concerned about your comment about a possible reduction of 6 db in volume using an XLR to RCA cable. I will have to e-mail Victor K. at BAT to get his thoughts on this issue. Thanks again to all responders!! Jim
