New Audio Research Reference 150 SE



I just heard from my AR dealer that a new Reference 150 SE that uses KT150s will start shipping out in early March. Did I miss this on another forum or is this new news? This might explain why they have not endorsed using the KT 150s in the current Reference lineup.

Kal responded. ARC will be making a formal announcement within a month or two.

The plan is to upgrade the ARC Ref 75, 150 and 250. Kal was a bit unclear what the changes will be other than the SE upgrades will include KT-150 tubes and misc circuit and component changes.
Well Well, I feel compelled to thrust an ice pick thought my left testicle just in case I am either dreaming or hallucinating.

An unequivocal responce from Obfuscation Central !!!!!

" I received the following from Kalvin at ARC

"Audio Research will announce new SE versions of the REF75, 150 and Ref 250 in March that will take advantage of the improved sound of the KT150.

Also, SE upgrades for existing REF 75, 150 and 250 amplifiers will also be announced. Factory upgrades will be made available as our supplies of the KT150 increase "
Tsushima1 .... I think it was you who said that the cost for a Ref 150 SE upgrade would be roughly $3000. If so, more than half the value would represents tubes ($1600, or 8 x $200/per tube). The other half ... who the heck knows.

Kal said he did not think changing out power or output trannies was part of the SE upgrade. Just other "proprietary" parts and circuit changes. I am dubious that ARC would try and stuff any more power supply caps into the chassis ... not enough real estate left.

Kal said that the SE upgrades will be available soon. Perhaps more details will be forthcoming.
Spoke to Kal today. He told me it was ok to put KT-150s into the Ref 150. Hallelujah ... Moschiach has arrived.

But wait ... there's more. The cost to upgrade the Ref 150 to the SE grade is $5000. Of course, that includes all new tubes --- KT-150s and 6H30s.

Kal said the objective of the SE upgrade is to tune the amp to take full advantage of the benefits of the KT-150 tube. Kal added that the improvement is on the order of going from the Ref 5 to the Ref 5 SE.

Five grand is a lot of scratch! The Ref 5 SE upgrade was only $2500.
