In general I don´t agree that tech-house is more "entrancing" than psychedelic and goa, but I see some of your points. But A LOT of tech-house simply lacks last drisle of openess in the sound that can lead the thoughts "away", and is directed too much at the club environment. That of course is also the problem in a lot of full on / prog and other types of music related the psychedelic scene. But in my mind they also left the psychedelic movement and became something else quite some time back, only the name sticks. But regarding "entrancement" I think the techno scene has more to offer than tech-house.

but of course some tech-house is very "entrancing" like "Masomenos - Juhuu":

Which I don't think can be said about "Johnny Corporate - In The Pocket" which was posted earlier which is also not tech-house as adressed earlier. I think that track is very far from being "trancy" actually...
