The System
Source – modified Cairn Soft Fog V2.
Mine is modified with a 2-nd transformer, LC Audio clock, Black Gate and OsCon capacitors instead chip stock ones, better RCA and power connectors and silver fuse. The results make it comparable to the Meridian G08. I did a direct comparison with the G08 and the sound of the Meridian is a little more sweet. The highs are not as sharp as my modified Cairn, which in my opinion, is what makes its tone more mild.
Amplifier – modified Antique Sound Lab Twin-Head Mark III. Modified in this case with gold-ceramic tube sockets instead of plastic originals, DACT stepped potentiometer instead of the original Alps Blue, 4 Auricap capacitors in bypass tribe, again better RCA and power sockets, also silver fuse and better set of tubes. Originally there are only Sino's and NOS Russian 6N23/ECC88. Current set is: 2 x M8137-ECC83 Mullard, 2 x 350B Valve Art, 2 x 5AR4/GZ34 RCA “Big bottle”, 2 x CCa Simens & Halske and 2 x 2A3 Emission Labs “mesh”.
I had them both (E9 and GS-1000) through four days. Only the last day GS-1000 were tolerably heated. They need 400 hours, not even one less, to plays good.
