Hi, John. Here's the convoluted history of my amps, thanks for asking....
I started with a VAC 300.1a running Esoteric MG20 speakers (wow the transparency was too much for me!), then upgraded to the VAC Statement 450S and it was a definite step up....more holographic, more drive, more texture, more, more, more of the VAC goodness....and the tube heat ugggh. Then I auditioned a Hegel P30 which surprised the hell out of me. I was surprised by the little P30...it beat my VAC preamp...made my VAC 450S sound so much better through my Magico speakers...more extension, bigger, etc. One area it didn't beat the VAC was in harmonic texture. The beauty of VAC is a violin sounds like a violin - no electronic sheen that disrupts the illusion of musicians in your room. But the P30 (and the H30) brought a "bigness" of sound and grip especially on the low end that made me think my Magicos were playing midrange and above with the VAC. No heat and perfect synergy with the P30, I was ready to put the H30 into active duty and call it a day.
Then....Then....Then....and it is the biggest "THEN" I can write....along came Constellation Centaur (I'm listening to it right now). I don't have the words to express what I'm hearing. I didn't know it could sound this good. If Magico wanted to have powered S5s all they have to do is incorporate the Centaur and call it a day. It is everything and then some....but not too much. Gentle and strong at the same time. Full but precise. My woofers have no dust on them. ZERO, absolutely ZERO fatigue, but 1,000,000,000,000,000 percent detail and transparency. Smooth as a baby's bottom. I could go on and on and on. Best way i can describe is the Centaur with the Magico S5 speakers exceeds my expectations and obsessive perfection every time I hit play or drop the cue.
If I had to choose one word to describe the sound of the Centaur it would be "delectable"
