"Ken,I got the "Cryogenically" treated grade 6922. They sound better than my Siemen CCa. I would like to buy one more match pair for my X-CAN.
I would also like to buy a pair of 5814 to replace the tubes in my SLP-2002. I find Mullard CV4003 in your Web site. Does it sound
better than the RT or CIFTE? Do you have any better suggestion for me just like the "Cryogenically" treated grade 6922?.......CK in HK."
"Hello Ken
I wanted to give the tubes a good burn in before I wrote you, and boy I
don`t know what the cryo does to the tubes but they are more neutral and
much more open in the back of the sound stage then the none treated. I here
more inner detail and the hi`s were great on the none treated but on the
cryo`s it was superb. There is less congestion in the sound stage when
passages get complicated or full of instruments much more detail around
Images what a difference from the seimans Falcons. I will be ordering more
for future stock! Ken thank you very much for your advice and honesty and
great service. These tubes are fantastic!Best RegardsP HARRIS."
