Audio Research REF 110 or Ref 75


I have an ARC VT100MK2, and a pair of Wilson Watt Puppy 6.
Considering upgrade and was wondering what I would gain buy either of these amps. I have all ARC pre / CD and transparent cables.
What I would like to gain is a bit more control in the low end. A tighter bass punch if you will. While still maintaing the liquid tube sound in the mids.
I listen mostly to classic rock and jazz at lower volumes ( around 80 db ) sometimes I go louder. I considered a solid state amp, but I do love the sound of tubes.

Thank you

Thanks, I have a Audio Research LS26 Pre amp. Its not a REF 5 which I one day would like to have. But I assumed my amp being older would be the weakest link.
Vdosc,
Are these the correct specifications for your speaker?

Nominal impedance: 4 ohm
Woofers: 2 - 8 inch
Midrange: 1- 7 inch
Tweeter: 1 - 1 inch inverted titanium dome
Sensitivity: 92 dB (1 watt @ 1 meter)
Minimum Amplifier Power 7 watts per Channel
Weight: System Net: 324 lbs
Frequency Response: 21 Hz - 21 kHz (-3dB)
Its a tough choice because both pieces are very good, but there is still room to upgrade. If it were my choice, I would go with a new amp if I thought I didn't have enough power, or some other issue with the amp that you know you don't like. If you have no issues with the amp, a new preamp will usually make a bigger difference. Either way, you should seek more input. I have a lot of experience with your amp, but not so much with your preamp. Given that, I can't make a fair comparison. Overall, you have a very well matched system. Wilson/ARC go very well together if done right. Are you working with a dealer? That would be a big help.

Vdosc, take a look at this Wilson Watt Puppy 6 review. Just above the section titled "Comparison" is a comment from Dave Gordon at Audio Research that talks about using the 8 ohm tap on the amp even though the speaker is 4 ohm. Even if you decide to get a new amp, it appears the speaker/amp combination may be best using the 8 ohm tap.
