12AU7 Genalex or Psvane for Cayin Hybrid Integrated H80A

I am not a tube expert, but I have actually listened to a PSVANE 12au7.  They are excellent tubes.  The PSVANE is not a warm sounding tube like some others.  It is definitely a very high resolution and detailed tube.  I think it's even better than the Electro-Harmonix.  The Electro-Harmonix is another high resolution and detailed tube, but it could be seen as somewhat sterile when compared to the PSVANE.   I have no idea how the sound compares to the Genalex.

johnss,
How does the ’VANE’ compare to GL? Don’t know if GE 5814 is compatible w/ my H80A. I do feel GL is warmer than EH in my system. EH is ’harder’ by comparison - more listener fatigue; GL much less fatigue.

auxinput,
I do prefer the warmth of the GL currently running; was put off by EH hardness once I replaced them w/ GL; didn’t know the difference until the swap. Was pleasantly surprised w/ 1st listen of GL. I am somewhat hesitant to go w/ Psvane since some say they are bright - but perhaps system dependent.

I already have incredible resolution/detail, and dynamics with very tight bass, yet still warm sounding to my ears. I may want to try something different, hence the Psvane under consideration.

Anyone actually carry these in stock near the Pacific Northwest? I am only finding them available to order online coming from HK/China.

How is the 12AU7 used in the Cayin, is it a phase splitter?

Just now discovered Viva Tubes with their 12au7 offerings. I think I may prefer to order from them since they are in mainland US. I would rather not have to wait for weeks on end for products from HK. However, Viva, although they do carry Psvane brand, they do not have the Psvane 12au7 even listed.

What others do you recommend considering in addition to Gold Lion & Psvane?

nitewulf,
Apologies, I'm not sure what a phase splitter is, but the H80A is a hybrid with a TUBE preamp section & SS power amp section. The 2 tubes 12au7 are input tubes for the preamp section.
