The sound is full and rich in detail. I put the new Shuguang Treasure KT88 tubes in Wednesday night. I have to admit the bass was a bit pudgy. I ran the amp for 48 hours. Friday night I sat and gave it a good listen and it is working out nicely. The bass is clean, full and fills the room. I'm digging it.
I don't know if these are better then the New Issue Gold Lion KT88.
I also got a Siemens 12AT7 in the VTA center spot. That is a nice tube in that spot. I'm not good with describing sound so I won't try... I just plugged this in and it sounded great.
