Balanced v unbalanced input to Ayre preamps

Ralph's (Atmasphere) comments regarding a differential balanced circuit eliminating cable artifacts is based on the balanced design supporting the 600 ohm standard, as Atmasphere designs do. It is my understanding that not all balanced designs support this standard.

Clio,

That is correct that some balanced designs don't support the 600 ohm standard.

dbphd,

i presently use balanced cables in my system because I have 2 meter cables from my dac to my pre and also from my pre to pwr amps.I have noticed a quieter noise floor vs rca cables in my system.You may need to try some balanced cables in your system and see.There is really not a right or wrong way to this subject it just depends on what works the best for you.If you are using rca cables longer than 2 meter or so you probably would want to use balanced if possible.

Ayre gear is optimized for balanced connections and always sounds best when run fully balanced. If the Oppo is truly balanced (dual differential), then you'll get the best results that way. 

Bob,
The surgery was successful, and I have not experienced any pain since.  The worst part was the 3-week taper off the opiates.

ciamara,
The Oppo 205 is claimed to be fully, i.e., dual differential, balanced.  I may use a passive switch for sharing a balanced input between the Sony HAP and the 205 until I get a KX-5 Twenty that has additional balanced inputs.
