Heads Up: ARC is introducing the new SP-20 in Fall

An excerpt from ARCDB web site:

"Tube stereo preamplifier.

"As a result of the ever-increasing demand for a full-function preamplifier with a level of performance substantially above that of the SP17, we are pleased to introduce the striking new SP20 vacuum-tube preamplifier. Influenced by some of our classic groundbreaking SP preamplifiers but with performance that is only achievable by our best LS- and PH-series designs, the SP20 offers inspirational performance combined with real value. ..."

MSRP is $9000 -- a veritable bargain. ;-(
You ARC people crack me up. I get it and I respect you but damn. ARC has to be the most prolific model developer ever. They certainly know how to maintain their customers interest.
Hey, don't forget the SP15. It also handles low output MC cartridges just fine and sounds great with NOS tubes.
No problem using a .23mV Kansui with a PH-6. The PH-6 has far more gain versus any of the older SP preamps you mention.

If the SP series will handle .2mV then any of the modern ARC phono preamps, i.e. PH-5, PH-6, PH-7, PH-8, etc., will work fine.

I know I have owned the SP-10, SP-14, PH-5, PH-6. The PH series are much, much better with LOMC(.2mV) versus any of the SP series. The SP-20 will have similar gain to the PH-6.
