I've just received my upgraded Clari-T back a couple of days ago.. The unit was upgraded with Blackgate caps and boy, I can tell you the improvements are not subtle! Before this I felt the amp stuggles at higher volumes with my no so efficient speakers (~89db) - sounding rather thin and not so well controlled esp in the lower end.
With the BGs the 'thinness' is pretty much gone (Adamay - are you reading this) and the sound now is much more 'robust', 'bold' and has much better control in the bass department. I know BGs are bastards to break-in - imaging is still a bit lacking and the HF/LF are still not as articulative - hope things will tighten up over time.
I felt that the BGs have also contributed to a harmonically richer sound with more texture.
For owners of Clari-T who want to take the already great amp to the next level - this is an upgrade I would highly recommended!!
