I have a Luxman MQ—38uc-se amp that came with Gold Lion KT-88s. I’ve had this as my reference system for a few years but was never truly satisfied with the sound. One tube started distorting so I ordered a quad of Ray Tubes Reserve KT-88s. What an incredible difference they made. Now I’m 100% blown away by the sound. Much more holographic, detailed yet rich luxurious

Good communication, product packaged very well, arrived on time.

The best price on the internet for a new Xduoo DP-10

Apos has excellent customer service with fast shipping.

Products look great, I could not use them yet, so I can not say anything more. Those were may first tubes but selection was easy. Ordering was perfect, any problem with my pay modes, Delivery was fast. Thank you for everything.
