Integraded Amp

I'm afraid I don't know of an integrated in that price range with tone controls. Paul's suggestion sounds the best to me as you keep your current integrated amp and the tone controls are completely switched out of the audio path when you don't need them.

It's funny though, since I got new speakers I'm starting to appreciate how well some of my 50s and 60s albums were recorded. The engineers had fewer toys at their disposal and it would appear that this was a good thing.

Good integrateds don't have tone controls as a general rule

...is another audiophile's noncense.
If tone controlls could be switched off the integrated is as good or even better than the one without them no matter what price range you're surfing through.

Another vote for the McIntosh MA6900. It has great controls and is extremely flexible (a must for a good preamp IMO). It also has a tone control bypass switch to remove them from the signal path if you so desire. Arthur

Musicmann, the A308 from Musical Fidelity does not have tone controls. As far as I know, nothing from Musical Fidelity has tone controls.

The best is to get a new or used Beringer DSP parametric computerized equalizer that goes for about $300-350 new and about $250 used. Try it via the loop and see how you like it. It is often that we try to pursue the undescribable just to later figure out that we might actually wind up with a worser sound quality, as well as wasted money.

MF stuff, is in a different league than the Logos. The Mac, if you are interested might be a decent compromise.

Check most of the audio systems in the virtual systems, not many have equalizers, except a Tact Digital DSP here and there.

The best option might be to buy an used Mac 6900 and use it for a while, before you decide to unload the Logos. You will lose little money in this sort of situation. 6900s maintain their value well, this is not the case with the Logos.
