BAT NOS Super Tubes


Has anyone with BAT equipment compared the 6H30-S BAT NOS Super Tubes to the standard 6H30-N new production tubes? The BAT NOS tubes cost $300 (these tubes are no longer made hence the price) a pop, maybe more now, and I am wondering how these tubes effect sound in comparison to the standard 6H30 production tubes. Thanks

Madfloyd, Do post your impressions. I think if there is not adequate bass, you have ruled-out the amp and preamp.

I've been going back-and-forth between 1 pair NOS and 2 pair NOS. I think my system is now synergizing with 2 pair, and I will probably add back the 3rd pair to see how that goes. I noticed an immediate difference in bass definition going from the 1st to 2nd pair. I thought there was too much bass for my system with all 4 pairs, but may need to listen again in light of some other changes.
Tried them last night - all 4 pairs. Lots of harmonics flying around the room. :-)

I agree that it might be a bit much with 4 pairs. So much sparkle on piano notes that it obscures the base texture of the instrument. Sonic candy if you will.

I will try tonight with less pairs (and some tube dampers which I just received from Elusive Disc).

I have no issues with bass with the REX; I think it's one of its strengths. Great preamp.
