Integrated Amp to match with Magico A3

Maybe a bit off the beaten path and a lot cheaper than the normal selections, but I would suggest you consider something like a tube/ss hybrid like a Musical Fidelity Tri-Vista. I think TMR has one for around $2K. Mine has responded well to cable changes and fuse upgrades, adding refinement and detail. The Magicos I have heard (with either Soluution or CH Precision), were accurate but a little dry and congested, and could benefit from some warmth. Disclosure - I find myself leaning more to the wide-open sound of tubes and hi-efficiency as I am getting older, (probably losing some high frequency hearing) and everybody hears differently.  Good luck.

I purchased the Gryphon Diablo 120 with the optional DAC for my Magico A3s. I did not demo the Hegel 360 or 590, which I had hoped I could do before making my decision. I really liked the T+A 3100, but it was beyond my budget.

T+A will be a great choice if you can afford it. The Rega Osiris analog integrated amp (no DAC) will also be a great choice for the Magico A3. The Osiris is Rega's flagship integrated amp and it retails for $10k new. 

I consider it a benefit to have an integrated amp with no DAC, though it's good to have the option of adding one internally if desired. That way I would not paying for a DAC if going with an external unit. The T+A is well beyond my budget, but used ones get into the ballpark of what I am willing to spend. Thanks again, everyone, for the responses. So much to consider...   :)

Sinewaveron:  Can you at least tell us what mode you're running your Vitus in?  is it pumping out 25 WPC or 150 WPC and if the latter, do you feel this is better than the RI-101?
