Please Recommend a Low Gain Solid State Amp ARC

Hi all,

The amplifier I am using is a McCormack DNA-125, which has 30db of gain. I have an Audio Research SP8 MkII preamplifier. I had Audio Research lower the gain in my SP8 recently, but needless to say, the volume through my Vandersteen 3A Signatures still gets loud in a hurry. I was wondering if someone could please recommend a low gain, solid state Audio Research amplifier that is rated between 100-200 watts per channel? I do not want a tube amplifier, and I do not want to get rid of my precious (SP8 MkII).

Thank you!

lowering gain of ARC is bad idea.

Hi Guys,

Thank you for your help. I am using a Marantz SA8001 for my source. I believe its analog output level is 2.3V RMS.

Marakanetz,
Why do you think lowering the gain of the SP8 is a bad idea?

You may want to call Calvin at ARC. He might have some practical solutions. I mention in passing that the SP-8 is a bit dated. If you love your amp, may be you should switch out the pre. I am not suggesting that you get rid of the amp and keep the SP-8, but I am mentioning in passing that ARC gear works synergistically well together. If you love the SP-8, consider an ARC amp, even a used one. By the way, have you had ARC go over your SP-8 recently. Old gear oftentimes needs a freshening up, especially the caps. Something to think about.

Bad idea since the preamp will not be stable. It's been designed for a specific feedback and increasing it to lower the gain may bring amp to oscillation.

I had ARC reduce the gain on my SP8 a couple months ago. I was told by the service manager that they do lots of gain reductions on SP8's and their other older preamps. ARC said that reducin gain might lead to a slight loss of transparency, but that it would not be noticeable. ARC also replaced all of the original caps with new Nichicons. One of the caps was indeed faulty.
