I think you've been peeking in my bedroom.
I often wonder why people make such a thing of the treble peak when it is, as you suggest, quite effectively addressed by tone controls. Answer of course is that most people use dedicated HP amps, which is another mystery I've been unable to solve, In my view a good integrated or receiver (I use a Marantz SR4023 stereo receiver) can give results as good as any mid-tier dedicated amp. plus giving the convenience of remote volume (in 1db increments yet!) and switchable tone controls. I use -2db treble and +2db bass, which just takes the sting off the treble without losing bite or detail and gives a slightly fuller sound without muddying the bass. Simple Solution No. 463.
Oh, I apologise to the OP if I sounded a bit cranky in my answer. Must've been a bad day or something.
