What wood is your VC? I am waiting on my sapele VC now. The wait is killing me. I'm only about 16 or 17 days in. Zach said they are out of the machining phase so that is good to hear. Maybe not to much longer.
I don't agree. I found the Liric quite forward in the upper mids, and that made me sell it. Crin just published measurements that confirm how I heard them, a peak at 2-3k. The FR of the two headphones is quite different. They are quite complementary, the VC being laid back, the Liric more energetic. (A little too energetic for me, unfortunately..)

Build quality and comfort are the closest I've seen to them being on par.
Weight distribution and all day listenability are a wash. Both are on par.
Detail retrieval and overall tuning goes to the VC but I think the Liric is the closest I've heard to VC level in another closed back.
I agree with your point of them being complimentary but I've been back and forth with these for a couple days and I couldn't tell you which one I personally enjoy listening to more.
I recently bought an Ampsandsound Rockwell tube amp primarily for use with my Verite Closed. What I really like about this particular tube amp is that it has 5 impedance taps of 8/16/32/100/300 ohms so that I can pair it with all of my headphones. But, I am getting quite a bit of noise and microphonics on the 300 ohm tap. It sounds best with it, but to reduce the noise, I dropped down to 100 ohms and adjusted the volume pot down and increased my pre-amp to get the right volume.
My question is this. Is there anything I can do to reduce the noise? I am using the ZMF 2K Copper cable. Would a shielded cable or some type of power conditioner help reduce noise? Thanks!

What does the noise sound like? Hum? Buzz? If so, what frequency? Any noise will be worst on the high-impedance tap as it has the lowest turns ratio on the output transformers, which will also step down noise. Microphonics typically be tube dependent, so that should be easily fixable by swapping the tubes.

More like a buzz sound. There are hum pots on the amp, so I adjust those to get rid of the 60hz hum. There is another layer of buzzing that is a bit higher in frequency than the hum. Sounds like a tesla coil. I rolled tubes and the microphonics is gone. Thanks for that tip.
I think I found a solution. I am running my Chord Hugo TT2 in preamp mode and I set the volume pot on the amp as high as it will go before there is that buzzing noise. Currently about 2 pm on the tube amp. Then, I use the TT2 to volume control and most of the buzzing sound is gone.
Edited to note: I can run my Susvara using this method and the tube amp volume pot is at max volume. This sound is a lot better than connecting directly to the TT2 in headphone mode.

If it is 120Hz buzz, most likely leftover unfiltered ripple from the power supply, but could also be rectifier pulses being coupled into the signal path. In either case, that will be design and layout dependent, so not easily fixed. 6SL7 > 6B4G is a lot of gain for a headphone amp using something like a 3K:300ohm output transformer, I'd imagine with a typical 2Vrms DAC input (aka no preamp), the volume control is very sensitive on the 300ohm tap. The noise floor is going to be high on the 300ohm tap given the high gain in this amplifier. I think you can play with setting the preamp output and adjusting the amplifier volume control as you already are, or use the 100ohm tap, but not likely there will be a way to easily fix the noise on the 300ohm tap completely unless you discover it is not from the amp itself. Have a listen to some recordings of 120Hz buzz / ripple (I'm sure there are videos on YouTube) and see if it sounds the same as the noise in your amp.
The buzz/hum/etc is exactly why I went with Solid State. I have a lot, a lot of experience with tubes after having played guitar for the better part of 20 years. I love my tube amps and have had probably more than 20 amps but they always had issues with buzz/hum and I spent many hours and many dollars trying to fix it to no avail. Maybe it's different with headphone amps vs. guitar amps but just didn't wanna risk that for the $$
