RonP thanks for this thread…fortunately for me my Emotiva XSP1 Gen 2 preamp has
a defeatable tone control…which when I turn it on particularly at lower sound levels
the sound stage just opens right up…hf and lf left at trim neutral setting
The way the tone control adjustments are designed…
High-Frequency and Low-Frequency Trims:
HF Trim inflection point: 4 kHz.
HF Trim adjustment range: -3 dB to +3 dB @ 12 kHz in 1 dB steps.
LF Trim inflection point: 200 Hz.
LF Trim adjustment range: -3 dB to +3 dB @ 50 Hz in 1 dB steps.
have minimal impact on the overall response…yet do provide sufficient
adjustment …
Needless to say I enjoy using them…
