Fully balanced SS pre for McIntosh 402?


I sure would like to stay true to McIntosh but C500 is way too expencive and C200 is discontinued. What other fully balanced solid state pre's should I consider if I like the Mac sound. Source is McIntosh MCD301 and speakers Sonus Faber Grand Piano. Thanx!

Only fully balanced McIntosh preamps that are less than the C500 are-C100/C200 both are discontinued but can be found used.

The C46 is not fully balanced.
Is the MC402 itself balanced? I run a c2300 to mine with good result (using balanced cables). I use a balanced DAC as well to the preamp.
