Having listened to my gears switched back and forth for some time. I can now tell what my preferences are, based on the time I ended up listening to each of them.
- Ella pull-push valve amp
Used most for audiophile recordings;
(Chinese KT88/6DJ8; Russian 6SN7GT; upgraded with AudioNote caps in the signal path; Available both in HongKong and US as complete kit for about US$600 including upgrades)
- Nirvana AKSA100 SS amp
Used most for pop music, particularly those mixed and with electric instruments; played at high volumes.
(for about AU$1200, including kits and self supplied parts)
- SiliconChips 15W class A SS amp
Used most for slow and soft music like blues and solo strings; played at late night at low volumes.
(Upgraded all caps with Panasonic and Elna Starget etc; for about AU$600 including kits and self supplied parts and upgrades)
All of them are driven by an upgraded GK-1 and helped by an REL active subwoofer. An Ultra-Curve Pro DSP 8024 is also used in the digital front for room correction and system balance, which makes significant differences in final sound quality.
