"Don't any of your DACs have high quality analog volume controls?"The MSB Technology Analog DAC, but there are some real limits with this DAC.
My Ayre MX-R amps have only balanced inputs. The Analog DAC's balanced outputs are a compromise. I guess one could solve the issue by purchasing an MSB Platinum or Diamond DAC.

Understood.
If you really did want to pursue a passive approach, which I believe would absolutely yield the very best results there are several SOTA passives with balanced and single ended inputs and outputs.
Side note..if you are not running a system balanced from source to amp, I don't see the point.
there are very few passives with balanced constant impedance operation that has fine steps. My Placette does 0.1dV above a certain volume and 1dB below that.
1 dB is simply not enough.
Apart from the Placette, I have a Carver Lightstar Direct which does not have the all Vishay resistors that the former has. It does 0.5 dB balanced passive and the active unbalanced line sounds poor in comparison.
Music First's TVC's are superb and the same with Townshend.
For Light based, you should check out Tortuga.
From Townshend website:
''Input impedance is dependent upon the load impedance and gain setting. So, with a power amplifier having 20kohm input impedance (typical
The Allegri Passive Autotransformer has a six position input selector, a mute switch and a 24 position volume control with intervals chosen to cover a wide range of volume levels in different systems''
Thus:
Variable Impedance
24 steps far too coarse
These are unacceptable features for me because they create major issues in use.
Thailand seems to be the source of many of these TLV transformers and one can buy them to experiment with. As I said, the wirelooms created in assembly are not nice for mutual and external pickup.
