ampllifier design

my reason for selecting the 6cg7, especially tungsol and rca, circa 1960's:

i have found that of the three tube types, 6922, 6dj8 and 6cg7, the latter, in my experience has , subjectively been experienced by me as most balanced in frequency response.

as has been stated, the circuit is most important and i would attempt to create as balanced a frequency response as possible.

hi 9rw:

i seek a balanced frequency response. in the past i have found that many components exhibited an emphasis in the 1000 hz to 3000 hz region. recently i auditioned two, the audionote kits l3 line stage preamp and an implementation of a sabre 32 bit dac chip, which i found balanced in frequency response. both components created resolution and lack of a euphonic signature which i found compatible with many of my problem cds. i can configure my stereo system to sound "soft" and subtractive in the upper mid/treble. when reviewing i attempt to create as uncolored a perspective as possible.

in terms of personal listening, i have, in effect two stereo systems. one is obviously colored, while the other is open, dimensional and relatively balanced in frequency response. the quad esl 57 (quads unlimited version) represents the "linear" sounding stereo system, while replacing the quads with magnepan 1.6 and replacing the vtl deluxe 120 monos with consonance monos creates the "color" .

you can read my review of the audionote preamp on audiophilia.com. the sabre dac chip has been set up in dac form, including a linear power supply and is currently under review. i welcome your feedback.
