You can download the manual directly from the Krell site at:
KRS-1A manual is sufficient.
I had the KRS-2 preamp which already had the largest capacitance I ever saw in a pre-amp (apart from the Dynaudio Arbiter which had capacitors the size of beer cans and 8 of them) saw the KRS-1 Balanced is even more overkill.
Important difference are the Spectrol stereo pots in each main module making it true balanced.
Try to get a pair of Krell KRS-200´s and your Class A king all the way!
