Preamps ... no bass or treble control?

I never used bass and treble even when my componets had them, it just never seemed possible to jigger one sound without molesting the whole signature, I would say for sure that when you get into mid and hi fi that tone controls are not normal to see on equipment

Staying true to the music would also mean that it was recorded direct to disc, without a mixing board, overdubs, level changes before the master, etc. Think Sheffield lab products.
Now, almost everything else has been manipulated in some degree by the recording engineer. I prefer tone controls to tame harsh treble, for example. My McIntosh C22 re-issue from the 90's has tone controls, but in the 12 o'clock position, they are out of the circuit.

Best of both worlds?

....When tone controls are at 12 o'clock ....can one generally expext the tone controls to be out of the circuit....or is that an extra feature on your Mac

Thanks for the feedback. The Adcom is an older GFA-545. I'm thinking of getting some Tyler Linbrook Signature speakers. If I do, I will be looking to replace the Adcom shortly thereafter.

at 12 oclock they are out of signal.....pretty cool
