Thanks, I normally listen at low to median level, I can try loud, and it may bring out some more details?yes, though I am not really need a lot loud bass, I plan on buying a subwoofer, just to complement the maggies, either:
Rythmik F12 Direct Servo subwoofer - Signature Editio
or SVS SB13 ultra.so far, it seems to me that Rythmik might be a better fit with the planar speakers.
Any suggestions?
As for Emotiva, I actually just bought XPA-2 for 4 days, and found out there is a humming noise, very minor, but it is there. That was why I come here and thinking about buying a better amplifier, though, I actually have no idea if these much more expensive equipments would have a similar noise issue?

Get a sealed sub for maggies.
Humming noise from an amp could mean power problems. (DC offset or not fully sinusoidal AC input?)
The transformers on the larger Emotiva amps will physically hum if there are problems with a dirty signal in the house.
Thanks, yes, Planning on buying Rythmik F12 Direct Servo subwoofer
I believe it is a sealed one.
The amplifier is functioning fine, I think this noise might be typical for the emotiva, and I have read in other forum, they also complained about the minor noise you can hear very clearly when you move you ear close by, say, 10-20 inches away, and I am wondering if those MagTech or other more expensive ones are clear from such noise.
That appears to be a QC issue with the particular XPA model, See if other models in the series are known for this problem. They have good reviews and user experiences in general and their price advantage is from the direct sale business model and low cost locations for labor. What was new about them was their success in doing this at a high level of quality. .
Re subwoofers, stick to sealed ones. Good values are available from SVS and Parts Express' Dayton brand.
If you go with a subwoofer and don't listen particularly loudly then you are much more flexible with power amps and get a better quality vs. raw power.
Thanks, yes, if I can detect the difference of 3.7 and 1.7, I will consider 3.7, and use sealed-powered subwoofers. In term of better quality amplifiers for 3.7: what are your selections?
The difference with a sub is that you can go from running the same amp components at class A rather than AB, and get better SQ. E.g.Pass Labs - getting a pair of XA series monoblocks instead of a large X series amp - e.g. Getting an XA160.5 pair instead of an X350.5 and getting the advantage of class A operation but at 1/2 the rated power.
There are many high bias class A/AB amps biased to operate in class A into the the 20-50watts range and having overall power of 150 w to 3-400 w.
Out of the high marquee level brands I think Classe Theta and Mark Levinson. Krell class A amps, Boulder. Also Coda (high bias class AB), Parasound Halo, Plinius, Hegel, Symphonic Line, Spectral
On the other hand you can go for tube amps like the VTL Rogue or ARC at the near 200 watt range if you have a sub .
No noise on the EPA1 ! Dead silent at all levels..
Good for you! I guess I would have to return this amazon purchase, Amazon currently sold out it.
