Would using RCA to XLR conectors screw up sound?


Just was perusing ads and saw an amp I was thinking of giving a twirl.Seller says it was made special with XLR inputs ONLY and os "fully balanced" (I'd have to check with manufacturer as I have two components now with bot connections and circut topology is notbalanced).I read in Hartley's high end book that going form balanced and unblanced back in forth in chain can do more harm than good and one might want to keep it single ended all the way through to avoid this.I wondering if anyboy has a take on this.It sure would be at least to use a long ass cable to go form the rack to the power amp between speakers.Opinions?

This is a constant topic of debate among local audiophiles here in Phoenix. I own a Rowland Model 2 amplifier. It is fully balanced & has ONLY balanced inputs. I do have balanced to single ended (RCA) adapters, that allow me to use it with preamps that have only RCA outputs.
I'm now using an Adcom GFP 750 preamp. It is fully balanced & also has single ended inputs & outputs.
IF you buy a fully balanced amp & don't use it with a fully balanced preamp, your not taking advantage of all the cicuitry in the amp. The noise floor may go up if you don't stay balanced with the preamp. This is a coin toss-some non-balanced preamps are so quiet the noise floor won't rise anyway..
Read a couple reviews on the amp - see what equipment it was reviewed with. You might even call the manufacturer.
Jeff Rowland & Nelson Pass believe strongly in fully balanced circuits. I met Mr. Rowland at my local dealer. He was very down to earth and easy to talk to.
Try to remember there are amps & preamps that may have balanced inputs & outputs, that are not truly balanced.
You need to verify the "balanced" status by reading the input & output impedence figures.
