Jitter Of New Mac Mini Optical Line Out Improved?
Well, that explains everything. I just got a new mac mini and I have it running wav files via audirvana plusinto a Neko DAC via toslink, and my system has never sounded so good. 
Conrad Johnson PV10A Mods/upgrades
Bob modded out my CJ MF2250 and it sounded much better. I'm still trying to decide whether or not to send my PV-15 to Bob or to CJ for the cap upgrades. Tough decision. Bob's version will no doubt be superior, but it will cost more as well. 
Headphones? Anyone?
I just got a pair of Shure SRH-1440's in the mail for $300. Return item, open box. What a deal!! I would agree with those who say this is a midrange-centric listening experience. The midrange is lush. The highs are extended without being harsh or ... 
Headphones? Anyone?
I have a pair of Grado RS2i's, which I really like. You can get a set used in the $300 range. The PS500 seems to be popular because it's a bit less bright than the Grado house sound, but you might not be able to get a used pair. The 225 seems to b... 
Zu Omen or Tekton Lore

CJ PV-14L replacement tubes
I would stick with the CJ 8080's if I were you. They bought up a bunch of the NOS stock. The 8080 is a ruggerized military tube used in British walkie talkies. I have a pair in my CJ Pv-15.

Why don't you pull the tubes and let us know what kind they are, then we could offer suggestions.

Yes it is fairly straightforward, but you will need to pull the cover and ID the tubes for us. 
Revisiting Tube Recommendations for Cayin TA-30
You may want to try the NOS 6p3s-e tubes from Jim McShane. They are cheaper than the EH 6CA7's and sound better. 
Upscaling Speakers, Downscaling Amp...What to Do?
I second the jim nicholls, JWN amp advice. 
EL34 upgrade
In that case, you should be able to get a very, very good amplifier for around $1000. 
EL34 upgrade
Mikirob, Jim's amps are IMO one of the best values in audio. Send him an email, tell him what you are looking for, and he will give you a price. You will be very surprised at how reasonable and affordable his amps are. For example, I only paid $15... 
EL34 upgrade
Mikirob--I have a JWN amp built by Jim Nicholls. He has told me it is his best effort to date. Here is a review of his work.
