Audio Research pre-amps?

Hello,

I have an Audio Research LS-3 pre-amp paired with McIntosh MC60 mono-blocks. I use an NAD 546BEE CD player and have Nola Boxer speakers on Skylan stands filled with floor dry. The cables are Kimber Heros and 4PRs...and I just added a REL T7 subwoofer.

Anyhoo...my latest thinking is that the system is a just a touch too bright...not much-just a little.

So my question is: I'd like to stick with an ARC pre-amp. Is there a model I should look for that might be a touch warmer? Maybe a tube version? Nothing too new and under $2000..$2500?

Thanks much,
Aaron

If you haven't already done so, my suggestion is that before replacing anything you try the 4 ohm taps on the amplifiers, even though the speakers are nominally rated at 8 ohms.

I couldn't find an impedance vs. frequency curve for the Boxer, but small two-ways often have a significantly lower impedance at low frequencies than at high frequencies. If that is the case with the Boxer, using the 4 ohm taps of your MC60's will result in a less bright sound than using the 8 ohm taps.
