RE: Two inexpensive DAC/headphone amps - initial impressions (warning: long post)

I saw that you got another amp. I thought I would just let you know that
The 6AK5 vacuum tube is a miniature 7-pin sharp-cutoff pentode used as RF or IF amplifier especially in high-frequency wide-band applications at frequencies up to 400 MHz. A lot of mfrs are using R/F tubes in these Applications latley they are cheaper and easily obtainable and using a 'Starved plate low voltage desighn ' I have to wonder if an old School 12AX7 at full plate volts being a triode might sound better unless of course and likely they are running the pentode in
triode mode .
