DCS Rossini and Clock landed today. Just started burning in. Mick the owner of Quintessence Audio in Chicago personally delivered and set it up. I highly recommend Quintessence to everybody.

@HiFiGuy528 would having a pair of Sennheiser hd800s and hd820 plugged in at the same time be fine? one via 4 pin xlr and one 1/4". Both are 300 ohm impedance.
Is it normal that I hear some hum / noises when I have the sennheiser hd800s / 820 plugged in when no music is playing? With the 1266TC it is dead silent when there is no music playing.
That hum(probably transformer) afflicts numerous WA33. With my own a hum could be heard between tracks with my ZMF Verite open but dead silence(relatively) with my LCD-4.
I had strange effect hum with EML 300 in right and I flipped the tubes and hum went away, KR tubes silent ACME silent. With ZMF there's hum audible with no music playing and it's from both channels. My planars are quite.
I have some hum for the first 30 seconds while the WA33 turns on, but only then, and only with the HD800s and th900mk2s. The hum goes away after the WA33 is fully turned on.
Using the exact same tubes, I had some persistent hum with my original standard edition (and the wa33 itself buzzed a bit, which apparently is common). But no persistent hum or buzzing with the elite edition. I don’t know if I just got lucky with the elite having no hum or buzzing, or the elite transformers are less susceptible to such hum.
So my hum is there during the first 15 minutes with any high sensitivity headphone. It’s in right channel. So hopefully burn in will eventually give me silence during warm up. It’s different from the hum on zmf.
The hum with my hd800s / 820 are much louder on H impedance than when on L impedance. With 300ohm headphones impedance should be on H yea?
Does this impedance setting really just give more gain or is there something else going on? Level is on L for senn's. Cant really go higher than 9am on the volume knob for the senn's. No issues with 1266TC though.
I believe Woo recommends H impedance setting for headphones over 100 ohms. But of course try both and see which sounds better to you. Can't hurt anything.
