Nope. That's backwards. The RIAA equalization curve for an amplifier
phono input boosts the lows and attenuates the highs.

In this case, it sounds like too much highs, which would not fit the
curve.





I thought it was the other way round in this case, i.e. that the highs were
unintelligible (like fluff around a needle, according to Mr. Cook).
