I found the original Chinese tubes to be a bit "hard" sounding with transistor like "harshness", although all the frequencies are evenly presented. The Siemens 7308 (Upscale Audio, about $55 each, USA Phillips made?) have a more pleasant rolly-polly PRAT-ness to them but are not very resolving. Siemens CCa (later mid-seventies version, blue & orange box, Parts Conexion $120 each) are much more resolving but at expense of elevated upper mid-range which I find very objectionable- have not tried the preferred earlier blue-yellow box type yet. Am now using JJ E88cc which give a level/even/consistent presentation, not the most dynamic or resolving but a liveable compromise (About $18 each). Will try others as time goes by, good luck, Mike.
Dk Design VS-1 mkII what tubes are you using??
I am hoping to get advice from current owners of the DK Design VS-1 mkII integrated amplifier on which nos tubes are sounding best. I will be purchasing tubes in the next few days and would love to know specific experiences from my audiogon friends. If you let me know who you purchased the tubes from that would be very helpful also. Thanks and can't wait to start tube rolling for the first time.
