Hi all,
Better late than never. I've run all the above in my Modwright Oppo PS9.9 and recently have been using the GEC U52. It is superb with great detail, great bass, layering, separation and a huge soundstage....it also adds some body and weight to the music that wasn't there with most others, similar to the Philips 5R4GY in that regard but more refined. I was disappointed as well as a bit surprised that the "Holy Grail" Western Electric 422A seemed a bit bright and harsh. Anybody else here find that? Could be that it had tested new so not run in as yet. I plan on running it for 100 hours starting this weekend and will see what transpires, but for now the U52 is going to be tough to top!
Thanks
