Ok, thanks for the help guys, what I was looking for was a little better bass impact, and a "fuller" and "crispier" sound, maybe some soundstage..
But if it doesent really do much to the ms1i:s I think i'll wait and see what to do. I'd rather spend my money in something else in that case :P
Do you have any suggestions in another amp that would fit me? I'm quite low on cash
so anything mor expensive than the t3 would be a problem
In the T3 price range...hmmm...can't think of anything better than the T3.
Meier Headsix/XXS is another good one, but the price is going up with build quality and reputation.
A used iBasso P2, D3 or D2 Viper with new opamps would be better than a T3 or D2 Boa, which are still not bad with these phones. The D2 Boa slightly below the above as an amp only, but as a DAC/amp it's a little better choice than Lyrix Pro with DAC. The D2 Boa will also sound better with TF 10 pro than T3, where I think the T3 and TF 10 Pro together sound a little too forward for my tastes.
Top recommendations are even more expensive, like iBasso D4 and D10 which would beat all those listed above, but for over $240 - $290 shipped.
Going back to the affordable iBasso choices that are not discontinued, with MS-1 or other Grados the T3 and D2 Boa are still a better choice than the Vivid V1 and Nuforce Icon Mobile, which don't pair as well due to colorations of the phones and amp added together. Between those two amps, the MS-1/D2 Boa combo will give you better bass impact and soundstage than the T3 (same with TF 10 Pro).
The MS-1 are still a mid-fi headphone (but beating the SR-60 and AH-D501K), and so you want to consider what amp will work with any headphone upgrade you do in the future.
