@ct0517---Well, I do own two of Bruce’s speaker models, LFT-8b and LFT-4. My not having an ET arm is the result of long ago choosing the Townshend Rock as my turntable. A linear tracking arm can not be used with the Rock, due to the table’s damping trough.
I’m of the opinion that a system is best assembled from the two ends inward---the phono pickup and the loudspeaker (both transducers) first, then the tonearm and the power amp. I believe the speaker should be selected before the amp, the amp then chosen by it’s suitability for use with that speaker. Likewise, the pickup first, then an arm particularly appropriate for the chosen pickup.
Chris, as you know, I am also a long-time Quad ESL owner, and I got myself both a Bedini 25/25 and a pair of Atma-Sphere M60’s with which to power the Quads. I chose the Townshend Rock as my turntable because of my love of the Decca/London pickup; the Rock is THE table for the those pickups, for reasons I won’t go into here.
I saw and heard the Oracle Delphi/ET-2 and VPI HW-19 & TNT/ET-2 many times at Brooks Berdan’s shop (Brooks’ two favorite arms were the ET and the Graham). But since I prioritize the pickup over the arm, and the Rock is the best table for the pickup, never got myself an ET arm. I got the VPI HW-19 with the intent of installing the spare Townshend damping trough I have on it for a second London. While looking around for an arm to put on the VPI, I became aware of the TransFi Terminator. I was intrigued when I saw a London Reference mounted on the arm in pictures, and subsequently learned that TransFi owner/designer Vic used the Reference himself. Since the Terminator is only a little over a grand, I thought what the heck, I’ll give it a try. I have no idea how it compares to the ET arm, so if I end up liking the TransFi maybe I’ll consider looking into it. Though the ET and the TransFi are both linear-tracking air-bearing arms, they are very different from one another.
