@Taters ... now that is funny!!
@Jwm ... to some extent I get your point. I have traveled the long road of ARC product development. Many times, I scratched my head thinking, ... I don't get it. For example, moving from the PH-7 phono pre to the PH-8, was for me a bust. I happened to have liked the PH-7 a little bit better.
Same with my move from the Ref 3 to the Ref 5 (not SE). The Ref 5 was supposed to be in another league. Not sure which league, but I didn't think the Ref 5 was a revolutionary upgrade over the Ref 3.
All that said, if you were to take a sonic pic of my rig today as compared to 5 years ago, I think the cumulative and steady mods have put my electronics in a different and much better place.
But I do get your point ... and frustration.
As to the Ref 6, I surmise this may be a very different piece of kit. Reason: unlike the Ref 3, the Ref 5 and the Ref 5 SE, the ARC Ref 6 uses 3 versus 2 6h30 tubes in the gain circuit, aside from other changes in the power supply and so forth.
I look forward to reading honest retail owner comments in the near future. Unfortunately, as many members have fairly quibbled, many professional reviewer comments tend to be company advertisements for new products. I remember reading an early professional review of the Ref 5 (not SE). I recall the reviewer saying something to the effect (as paraphrased) that "The King is dead. Long live the King," when he heralded the coming of the Ref 5 (not SE). BS!!
