Yes, absolutely. Not as ultimately transparent as some, but very very smooth and nice to listen to with great harmonics. You really do have to jump to an ultra-expensive i/c such as quattro-fil to better it.
I do note that maggies sound really good with silver cables and tube equipment. Seems that the silver harshness does not really come out with that combination.
I used some cheap kimbers (thick brown and black weave cable - don't even know what they are) with mine and had great results.
