Gosh, just drained my wallet again.
After a recent purchase of a T1, I took another plunge and picked up a second-hand tube amp - Ting Feng 3PRO (literally means Hear the Wind in Chinese) which was in a very nice condition. TF is a DIY brand by a guy living and working near Guangzhou. The amp is highly regarded here in the headphone community in China but I think it's rarely known ouside the country. Tube fans here always compare it with those Chinese tube amps such as DarkVoice, La Figaro, and Little Dot whhich have already established their names overseas.
3 PRO is the top line of the brand at an online retail price of RMB4,980. It features 2xShu Guang 6H5C (mine are Russian equavelents), 2xTelefunken EF800 (the seller gave me two plus Siemens EF80), a 6.35 phone socket, a XLR socket (the amp is unbalanced), a pair of RCA inputs and a pair of RCA outputs. There is a higher bespoke 3PRO version which is modified to the customer's specifications at a cost of RMB2,000.
Soundwise, my initial impression is very positive. So many details, very dynamic but also smooth, no hush treble. People say it mates very well with T1. I feel HE500 has more chemistry with it. When adjusting the volume control to the very high, I can hear current noices. Otherwise it's quite dark. I tried it as the pre-amp on my speaker system. There is always audible background noices. But the sound is much fuller and richer in tones. One thing annoys me is the heat and power hunger of the beast. It also weigts like a tank.
Here are a few shots of my rig at its latest status.
