Amps for Vandersteen 3A Signature SS or Tube?

Would suggest you add the McCormack DNA-125 or DNA-225 to your list. Solid-state punch and detail, tube smoothness.

I would disaggree I think the tubes are better vansersteen are laid back and very detailed. I find with SS it makes them a bit harsh Tubes are just smoother and flow the muxic better. Then again I never had 3 I had 2cesig and now 5a's.

I would go out and listen to both, look at the pros and cons of tubes and then start narrowing your choice from there. It all depends on wht you like to hear.

How are speakers both "laid back and detailed"? I don't understand that description. 1, 2 a 3 Vandersteens are of a similar character. The 5 is a different class altogether. I still suggest solidstate to bring out the best the 3 has to offer but, if tubes are chosen, I would look for a modern design that is not as euphonic as most of the older amps tend to be.

Although I haven't heard the other amps, I think the Vandersteens sound great on the Ayre V-5X. They sound much much better on the Ayre V-5X evolution though.

I think Programmergeek means the detail is there, but without the harsh upper end.
There is a thing as too much "detail" to the point of driving you out of the room! My paradigm Signature S8s did that. The 2K cheaper Vandersteens simply sound better. Besides, I didn't care for the Chinese built cabinets! (they had a disclaimer about maintaining 40% humidity in your house or the warranty is void when the cabinet cracks!)

Personally, I have the 3a Sigs powered by a McIntosh MC275, 4 ohm taps. Pre-amp is a C22. Not only do they go very low, they also go up all the way in a natural, not overly aggressive presentation. I can listen for hours without fatigue.

I never had SS hooked up to them because I consider SS a step backwards. The MC275 DOES control the bass, goes l-o-w, has plenty of detail, extended highs. My MC240 did a good job, but the 275 a much better one.

As an extra note I have a pair of 1C speakers driven by a MAC1500 tube receiver. What an excellant combination for a smaller room!!

I don't think you can go wrong with a bulletproof Mc275.
