Recommendation for Integrated Amp with Tone Controls

Is used gear an option?
A restored "vintage" piece might be your best bang for the buck. The Sansui Integrateds seem to have a loyal following, and could be found within your budget. Accuphase and McIntosh gear of the same vintage might be a little outside your budget, but would be worth looking into.

A good friend who produces some of the live shows I mix has had a Vincent 236 for a while (uses the  Silverline Prelude main speakers I own, and it's where I first heard those) and it's a beast. The pics of these things don't convey how massive they are, and it sounds great (he loves the thing)…plus it has tubes in the front end so there's that. Getting a used one of these things is absolutely worth it if only for the "price per pound"…I have a Vincent/Kavent balanced preamp (Kavent S-33 same damn thing as the Vincent SA-93) with similar extreme heavy duty design (the preamp is clad in 1/4" aluminum, and it comes with a built in cigarette lighter…uh…wait…actually it doesn't, but still…) and it's amazingly good.

Actually the Sonos has an eq option in the settings.

Thanks chrshanl37! But I thought that only applied to the speakers with built in amps?

Take a look at the Marantz US | PM8005. It's a bit over your limit but it may be what you're looking for. I have a PM-15S2b and it does great for double duty (music and movies) and has the tone controls you desire.

I believe it (like my Reference Series) is made in Japan and not China.

All the best,
