ARC Ref 110 with KT 150 tubes

Bifwynne, thanks for the follow up. I'm in the market for a new preamp and the ARC REF 5SE is on my short list. I was concerned by some grumbling from owners who have received 6550we's as replacements and were not happy, so good news per your findings.
Cheers,
John

A recent clarification folks.

" My dealer answered my email this morning. It seems that Audio Research is being very tight lipped regarding the details however an upgrade will be available later this year and will run around $3,000 including KT150 tubes (for the Ref150). The upgrade price will include several parts upgrades but no specifics given. The new list price of the Ref150se will be $14,995 ($2,000 increase) which has been previously posted "

Just in case anyone is still wondering the KT150 is NOT recommended in the Ref 110. I was told this 2 weeks ago by ARC. 

I was  told buy Audio Research service  Center that the KT150. will work in the Audio Research Ref 210  Mono Amplifiers The Transformers Power supply on not strong enough, The Rev 110 Amp is the Stereo so the KT150 might not work in Amp also.

I need to make a correction about the KT150 Tube  it will not work in the Audio Research Rev 210 Amplifier, I Call Audio Research Service Center about this.
Sincerely

John.
