Post on the choke changes and what happened. I previously had these chokes in the DAC,,,,,,,
I dont know what they are, but they are really heavy like an Oil filled choke. And they have a similar kind of character. They give a beautiful liquidity and wetness to the sound. Like a Freed choke does, but not to the same extreme. When we were first dialling in the DAC, it was to drive my SS amps in the SGR speakers, and these chokes gave that system what it needed (SS amps can tend to be a little dry).
But this lovely liquidity and wetness comes at an expense, these chokes lack some top end clarity. This has become very obvious on the current Tannoy/Radford system. They are coming out of the DAC, but I am keeping them because in a different component, in a different part of the system, they could be magical. We need different sounding parts like this to dial things in.
I've changed the above chokes with some newer UTC chokes. There are a number of different UTC models. The ones I am using, are (I believe) to be the preferred choice for current model Killerdacs? Model H-72. Here are the pics.
These H-72 chokes are very nice sounding chokes. They have top end transparency, and simply a nice balanced natural sound.
