Tube Rectifier Comparison with SSHV in between

Vin= SSHV input / Vout= SSHV output

Because i am on vacation, i had the time to listen to two other tube rectifier i have.

The question, if there are still differences in sound with different tube rectifiers and the SSHV in between, is

YES !!!

Till now i used the Bendix 6101, a very nice sweet and soft sounding rectifier.

After i roll to the SED Winged "C" 5U3C (5U4-G) Black Plate rectifier,

...someone lift a invisible curtain...

Much more precision in the mids and highs and the soundstage open up in all directions.
Jesus, in comparison the Bendix sounds much to soft!

The Mullard GZ37/CV378 Coke Bottle has also the qualities of the 5UC3 Black Plate,
but is a bit softer sounding.

The only disadvantage of the 5UC3 is, no soft start... But hey, there are solutions for that on the planet!

	have you considered adapting the tube-i-zator to use a valve rectifer Oliver?

	so the reference PSU provides 140v for the tubes and ~ 14vdc x2 for the digital circuits?

No. The tube rectified B+ voltage is ~185VDC with two taps (SSHV input voltage for each channel). Additionally i have 4 SS rectified voltage lines. 3x ~15VDC and 1x ~25VDC (SSLV input voltage).
