Bob - in your opinion, what TYPE of amp sounds best with the Magico S5's? Tube? Class A? Class AB? Class D?
What a fun question that is......my answer is I don't know as I only have 150 hours on the S5's. At 500 hours I might think differently. But, at the 150 hour mark, in my room, with my system here is what I'm hearing-
SS- Goldmund 280 with Absolare pre - Clear, high resolution, plenty of power to light up the room, so AB SS sounds pretty good, especially with a tube pre.
Merrill Veritas with the Absolare pre - Ask Allen, he heard this, you would be surprised how good 700 watts, even class D watts sounds on the S5's. Big, powerful, full bodied, but dimensional and great midrange. Could easily live with this comibination.
Absolare pre/Absolare 52 Watt SET amps - I have my system optimized to get the most out of the SET's. The biggest issue for the SET's is the 700 sq. ft. room that is heavily dampened. Surprisingly enough they manage to play at around 95db and sound relaxed and they definitely do the SET magic, with articulation in a way that for me anyway, only an SET can do. Like the song said "Something in the way she moves". In a normally treated room that was a bit smaller than my space any SET lover would pick this combo every time.
Absolare pre driving Line Magnetic 100 Watt (KT 120's) push-pull amps. 3D gigantic holographic soundstage with high resolution, layering....quite intoxicating.
That's what I am hearing at the 150 hour mark. The truth is, personally I could actually live with each one of these combos, they all sound really great with no issues with any combination. In the last week I have had people listen to all of the above and I had one guy that loved the Merrill/Absolare, one guy loved the SET's.....as in three seconds he turned to me and said "Oh Wow". I just got the LM integrated yesterday, but someone heard it right out of the box with me and we were both sort of stunned at how well the S5's loved the 100 Watt push pull amps.
I honestly thing it's a preference thing....for me the answer is to have at least one tube option and then one SS option to switch back and forth every once in while. The great part about the S5's is that no matter what you connect, or at least anything that I have connected to them has been pure magic.
I know that if you drive the S5's with Vitus, D'Agostino, Constellation, VAC or really any top quality amp you are most likely going to get stunning results.
