You're right, and that also goes to 95% of psytrance/ambient releases to-day.
You want some good ambient, check biosphere.
Be sure to check the Biosphere/Deathprod split called Nordheim Transformed.
Oophoi is some good minimal ambient.
If you want lively stuff check Steve Roach, Michael Stearns, and vidna obmana.
Also, afaik, ishq are considered new age and not ambient
Cheers
PS: I almost forgot, one of the greatest albums evAAr, David helpling & Jon Jenkins - Treasure
