How did the GEC U709 change the sound? A lot of people say they don't really hear too much of a difference rolling rectifier tubes, but I haven't seen anyone actually roll high end ones like you did with the GEC ones.

Like I said, they are just being shipped today. They, however, have been highly recommended by Franatic who has them and whose musical opinion I very much
respect. That being said I've tried bunch of rectifiers on my WA2 and I certainly hear differences and have my favorites.

They ship today from England. Can't imagine my modest little system sounding much better but I'll let you know after they arrive.

Actually, the more revealing a system is (i.e. better) the more likely you are to hear a difference.  What rect. tube are you running now, just for reference?

I've gone thru quite a few and my preference has changed as I've changed some of the other tubes in the flotilla. When I first purchased the WA2 I started with Tung Sol 5998's and Philips Miniwatt (Holland) E188CC's. Initially went with the RFT EZ80 and then to the Brimar EZ80 black plates. I then got hooked on the Tung Sol 7236's for what was a bit smoother sound on my rig and ended up liking the Brimar EZ 81's with them . At the same time I moved from the E188CC Miniwatts to Amperex Holland pinched waists. Last major change was from the 7236's to the GEC 6AS7G's. With those I've been using Philips Miniwatt D-Getter (Holland) EZ81's. So as it stands now I'm waiting on the GEC U709's, and going with the GEC 6AS7G's, Miniwatt EZ81's and the new Telefunken E188CC's.
Can I take a breath now?

You must be in love with the Telefunken to change your signature like that

LMAO !!!  Yeah my pinched waists are mad at me.  And the Dutch government has recinded my vendor's permit for my food cart in downtown Heerlen.  Some countries just have thin skin.

I should fly this:

British tubes rule.................except for the WE 421A

The Marconi/GEC U709's have made it to San Francisco Fran.  Should have them early next week.
Will let you know.  I'm stoked.

Sorry to hear that Bill, I didn't mean to get personal.

Has anyone tried the 396A or 6N3P-E tubes?

It's a smaller 6922 compatible tube & needs an adapter to fit in the socket, but a lot of people are really hyping this.

Might be better than the Siemens CCA, Reflektors etc...

I haven't yet, but I just ordered the adapters.  I have numerous 396A types (WE 396A, GE 5 star, and the venerable Bendix Red Bank 6385 etc.) to try since that is what my buffered output uses on my CDP.

Can't wait to hear your impressions.
Either iFi was hyping them legit, or they just paired well with what iFi was making.

Bill, any word for us on the U709s in the WA2?

One was DOA and we're working on a replacement. Seller is fantastic so I'm sure we'll work it out. Very hard
tube to find, however.

Sorry to hear that, but that's what also makes this hobby so exciting... the thrill of the chase!
