Glad the KR 2A3s work for you! How do they compare to the Shuguang Nature Sounds with your LCD-3s?
They can be, but it depends on the amplifier too. With my EC 2A3 if I was tapping the case I would get an echo from the KR (and some other tube makes too). With the EC Studio, I am not getting this at all. This is using the same pair of KR with both.
Obviously unless someone has a hobby of tapping the case while listening this is not an issue during normal use.

Maybe they will stop being so microphonic?? My Shuguang Naturals were really sensitive like that. My dog's barking could set them off. Seems like they have gotten better over time. Is that possible??
The microphonic isn't really and issue except that I found it very difficult to adjust the pots for each tube because just the movement of the pot caused the microphonic making it difficult to hear if I was increasing or decreasing the hum. Even more confusing to me that vc1187 says they are his least microphonic tube. Oh well. I guess hand made means differences like these. I still love the tubes - even more after listening more. At first I wondered if they might be too analytical but I also notice there is a realism I haven't experienced with other tubes.
Experiences with 6 headphone amps, the HD650 and HE400i
If you look at my audio inventory, I have 2 headphone amps, 2 power amps, 2 prs monoblocks + a headphone adapter that can turn the 4 speaker amps into headphone amps.
I have never experienced a microphonic output tube in SET or PP in any amp. AVVT tubes had pretty poor QA, or so I am told. My solid plates do not have a problem. I've never owned a KR, but i do have some Shuggy KT88s and 300B, also no problems. You should have mailed the tubes back as soon as you received them. There really is no other cure.

They have a 90 day guarantee and I have reported to the seller (Tubedepot) and awaiting a response. I may return them as you suggest.
I just don't know yet if I prefer them to the Psvane WE275s or WR2A3s.
