I will look up the specs for my SS amp tonight. I am also getting a nice triode tube amp Friday and will play with that!
I also think the output or gain of the AH is an issue to look into. The version one owns and the use of XLR or RCA
connections perhaps changes the output or gain. Not sure if impedence changes.
Here are the specs from the AH site.
TP 2.1 TECHNICAL SPECIFICATIONS
Frequency Response: 10 Hz to 50kHz +1/-2 dB
Total Harmonic Distortion (THD): 0.05% @ 1 kHz, -20 dBv, A-weighted
Dynamic Range: Better than 90 dB
Signal to Noise Ratio: Better than 105 dB
Channel Separation: 90 dB @ 1 kHz
70 dB @ 10 kHz
Gain 20 dB or 10dB with B upgrade
Output Impedance: Less than 600 ohms
AC Voltage: 120 Volts
AC Frequency: 50/60 Hz.
I have the upgraded B(balanced?) and N version and use the XLR connectors. The gain is 1/2 or only 10 db instead of 20 db for RCA. I am not a tech guy and perhaps this means nothing but having to turn the knob higher to achieve the same volume.
My B version XLR connections sound better in my system vs the RCA. It is easy for me to compare both as I own both AH RCA and XLR cables.
My AH DAC has two settings for output a low and high gain. I use the lower setting. Not sure if this has any impact?
Love to hear from Victor on this latest subject.
Bill
