Not at all, plenty of power in reserve and yes good guess on the measurements! The Dyns are great at retrieving micro details, lots of air and separation and the Cherry amp just brings more of that.
First day I ran balanced out of my dac into the Cherry, no pre...incredible! I would prefer this but I’m lazy and missed my remote so hooked up the pre and still sounds amazing....
Yeah, with the KING STM, you should have PLENTY of clean power!
I had the 48v STM and it almost got me to where I wanted but not quite. I have Magnepan LRS's, which are VERY demanding and hard to drive! Tommy and I talked about moving up to the KING, then to a 2-CHerry, then we finally decided on his top of the line Golden Cherry monoblocks. In heaven with this combo! Tommy's electronics are high end! Not high priced. They're just stupid good!
And I had his DAC DAC 1HS and I had the EXACT same experience with the STM. When I went DAC straight to the STM and used the volume control on the STM!!!!! Holy smokes! It was so good! I mean a very noticeable difference. Switching back to my pre-amp for volume control still sounds spectacular, but not as good as going straight to the STM. The tradeoffs are convenience for sound quality.
Now owning the Golden Cherries, I have to use volume control but am getting a manual, balanced, passive preamp sent to me to try to interfere with the signal as little as possible. Should be as close to a straight pass through signal from source to amps. Here is my set up with STM and now.
