One issue I’m having is that when I turn the volume down I get a pop of distortion. I’m using a sachs preamp. I haven’t had this issue with any other speaker. It doesn’t happen every time but probably heard it 4-5 times. Mostly in the right channel but once in the left. Any thoughts?

@abd1,
they look beautiful in walnut (?) finish.

I get a pop every time I turn off/on the SIT-3. Though I haven’t discussed with Jon (Cube distributor) on this but I assumed its normal. Your issue seems a bit different. Did you try any other preamp ? Since you have the DS which has a VC, maybe try connecting directly to the amp and see if you face the same issue ?

How do you like the Canary M90 with the Cubes ?

I would describe the canary as “creamy” but with excellent detail. There’s a certain lit from within sound I’ve heard others describe but didn’t understand until I heard this amp. Voices are the best I’ve heard. Might be a touch polite but speakers are also new and need breaking in. The other speakers I used were 85db stand mounts while I was waiting for the Cubes so not a perfect match to judge but the Canary still sounded great with those. 
My room sucks with one speaker in a corner and the other open but the sound is centered. The cubes like being pushed back more then other speakers I’ve had and no toe in. I get better results pushing the speaker close to the side wall. Maybe better getting an early reflection point. Who knows, but the stage shrinks if I move it off the wall. When my wife and I both listen for extended time I move the open side speaker about 20” further out and the stage is lifelike in scale. We’re house hunting and I’m really hoping to get a better listening space whenever we find something.
