2-3K, Integrated or Seperates

I think 3K integrated should always be better than 3K separates, and probably are. That is, at the same price points the integrated should have better parts with lower chassis costs, and cabling costs compared with similarly priced separates, especially at the lower end of the price spectrum. If you were considering a low cost passive attenuator for your pre with a more expensive amp to equal the price point, you might be better with the separates.

I can't speak for the sound of the Red Wine as I have not heard it, but at the price point, using a passive attenuator for volume control on their integrated version(I think they use GoldPoint or DacT) seems like the best way to get the most bang for the buck and possibly the very best implementation of a passive pre as it does not require interconnects and should have minimal or no impedance matching issues. If the Red Wine sounds good and works well with your speakers, it should be very fine indeed and a good way to spend 2-3K
