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.
