Nordost and Triangle

I do have NOS input tubes but havent upgraded the el34s in it yet. That is a good idea to change carts I will look into it. Thanks.....

I run Shanling SP-80 amps with the stock EL34 output tubes. I think thses EL34s are the same as the ones in the Duntonic 3i, and I think they're a pretty good tube. If you try NOS EL34s I'd really be interested in your impressions, but so far I'm betting the driver tubes make much more difference.

I just want a couple extra of each tube on hand so if a tube goes out im not without music. So i will just get NOS el34s to try.......

Trianglezerius, I just went and checked out your system properly. I hope I may be frank. If you want more resolution from CDs, you will never get it from interconnects or anything else downstream. It is the source itself which is proving unsatisfactory.

I know this CDP from having spent an afternoon listening to it with BAT electronics and Martin Logan speakers. The owner subsequently upgraded to a Shanling player and in my view you could profitably consider doing something similar. I am sure you will be glad you did.

Please keep in mind, that the grade of wiring used internally with your Zerius speakers is that of the Triangle TC2250 2.5 mm2 oxygen-free multi-strand copper flat loudspeaker cable.

I would seriously consider using equal appropriate lengths of the TC2250 speaker cabling to your integrated tube amplifier, for the maximum permissible performance.
