Which integrated amp would you pick?

I don't know which Musical Fidelity you are speaking of. There is an M6500i and a M6si. Perhaps there was an M6 before this???
I have heard the M6500i. It is a dual mono design and it sounds truly amazing for an integrated amp. It will sound better than many mono amps paired with a preamp.
I have the Parasound A21 HALO amp and P3 preamp, which should not be that different than the new HALO integrated. This combo is as good as the MF, I think. I would listen to both the MF and the Parasound for comparison using your own ears.

Of course the speakers you will use should make a difference, but both amps have ample power. I would give the edge to the M6500i.

Krelldog,

Many here are correct. Many dealers will DEAL. Don’t ever accept advertised prices as many will go much lower. I think I bought my A21 and P3 for well under $600 the asking price for the combo. Amazingly, the legitimate dealer was on Ebay! But you must be very cautious on that site. I checked with Parasound directly to see if the dealer was one of theirs, for warranty purposes. Good luck. As a side note, I think Parasound makes very good gear for the money. As I have said I think John Curl is a legendary engineer. As such the HALO gear is very well designed.
I would be very surprised if you opted for the integrated by Parasound and did not think it measured up. But on the flip side of the coin, not everyone enjoys the same kind of equipment. I have a Line Magnetic Audio 216 integrated tube amp. Some have stated they do not like it at all, I think it's superb.

Krelldog,

What did you get?
