The D3a LCR phono and 10Y line stage are my 'classic' preamplifier combination. Here some photos of a recently finished set.
This preamp has quite some physical presence which the photos cannot really show. It comes in at a combined weight of about 80kg.
From left to right: Line stage power supply, line stage, phono stage and phono stage power supply.
Implemented in the gold/maroon red/smoked eucalyptus color combination.
The line stage has separate volume controls for left and right channels and in addition separate switches for each channel to adjust by 1dB. This allows fine volume and balance adjustment.

Although both this line and phone stage can be used separately with other equipment, they work extremely well together and are actually designed to complement each other.
