Does the Sony SCD-C555ES have build in test tone and channel level adjustment for all the channel independently? I read a sterephile review on this player it say it doesn't offer the channel adjustment independently only to shift one to another, You have to use a analog multichannel preamp with channel level adjust on it for it to work properly. I am sure my denon 5800 receiver doesn't offer channel adjustment for the EXT input 1 and 2 (it is real bypass). How are your owner of the 555ES overcame this problem? beside using the analog preamp with multichannel adjustment.
