I would love to get the 2.7 or 3.7 model in the future. The other Theils I have demoed are the 3.5 and 3.6, which were nice in their own ways, the 3.5 was maybe too flat sounding, not in a bad way but more like gigantic studio monitors. I liked the 1.6 a lot in the store, when i got it home it sounded Musical Fidelity amp the sound was really not even close. Many amps later I ended up with a coda amp which was like lifting a veil form the 1.6 where the is tons of clean bass and mids . I think the 2.4 should work well with this amp which is part of why I want to upgrade. I have been wanting to see what the next step up in the lineup would be like. I find the 1.6 to be very amazing on the highs, but the mids and lows seem to be slightly less full sounding in comparison to how the treble range feels so palpable.
