Is the GAT / ET5 hard on tubes?

Dang, Randy, I'll have to go back look, I don't remember off the top of my head.

Randy,
Actually, Myles just reminded me...it was Part Connexion.

All I can say is that mine improved the sound of my CT-5, giving it a slightly warmer tone and a fuller sound than the stock EH's.

Maybe I should try the DR's in my ACT2. Never thought of doing so.

They've certainly gone up a lot in price. I seem to remember buying them from Conus Audio maybe seven years ago for $50 each, now they have them listed for $175. Jeez.

I've had the regular 6H30π-EB version in the Pr. 140 as it breaks in but maybe it's time to try them again. At the time the DR's seemed a little smoother but also a bit more detailed. Previously, it wasn't a night'n'day kind of difference but with the new caps, it might be another story.

Getting back to the GAT/ET5 -- any interest in the CJ crowd with GL Reissue 6922's??? Have some in my stash that I was going to use in a Sonic Frontiers SFCD-1 player & never did.

Best

The Conus and Parts Connexion 6H30s are the same. They're not the same color lettering as any other 6H30 I've had.

I did try the 6H30π-DR's yesterday in the PR. 140. I don't know if it's the new Teflon caps or just me talking myself into it, but this time around I noticed a big difference between the two. The -DR's are superior in just about every way: dynamics, clarity, transparency, timbre and frequency extremes.

This is a picture of one the -EB's I was using on the left and the -DR on the right.



The -DR looks like what they have at both vendors mentioned. As far as the innards go, the -EB and -DR look the same. In an older post by Victor Khomenko at BAT on the Audio Asylum, he said the -DR's were tubes selected for military applications and had better specifications than the -EB's.

They are awfully expensive.

Joe, your experiences with the DRs parallel mine exactly in my CT-5, interestingly enough. I also noticed a fuller, more natural presentation than the non-DR tubes.

Joe and Ray...

Got the Tele ECC88s today. Listened to some music with the EH6922s in for comparison then plugged in the Teles. One has a very low level, just the smallest bit of hum but do they sound terrific. I have to plant my ear on the speaker to hear the hum but the increased transparency is all over the room at all volume levels. Maybe all this gets better with some break-in time.

Ray... let me know how yours sound. I'm really impressed with the increase in low volume transparency. Still plenty of bottom end. I'm using my PR350 to start as it tends to be a bit more ruthless with detail. Have a meeting tonight so tomorrow will be the trial with the LP140s.
