Best tubes for ARC LS16 preamp

THANKS FO RTHE RESPONSE,I PREFER A VERY DETAILED HIGH END,LOW DISTORTION WITH A SOUND LEANING TOWARD THE WARM SIDE.HONESTLY DON'T KNOW WHAT YOU MEAN BY LINEAR ,I'VE HEARD THE TERM BEFORE ...THANKS

Linear would refer to a very clean, extremely "flat" tonal response with minimal tube warmth. For that sound the US Military Amperex 7308 CEP is one of the most accurate of this design type.

For Joeavid, very detailed high end with low distortion and good warmth, I would try Siemens 6922 Cca with gold pins.

No money would probably do well with the same tube, if the top end is too lacking in warmth for either of you, the Mullard (white dot if possible) 6922 gold pin is what I am running in my preamp. It is not as fast and extended as the Siemens, but warmer like a Telefunken with a more recessed midrange.

thanks for the suggestions ,i just ordered a siemens nos ,the cca was a bit too pricey so i went w/the 70's stock,platinium,acording to joe's tube lore,it'll still be an improvement,thanks

I have an LS-16 with the original factory tubes. Where would you suggest to buy new tubes?

Joeavid...please let us know what differences you notice when you get the new tubes going.

Does anyone have feedback on the AR upgrade ($1095) for the LS-16?

Thanks

I´m also curious to know how the original LS16 stack up to the MKII status.

Thanks,
