The HP manifold for my ET-Two 2.0 arm arrived from Bruce yesterday. After a much easier-than-anticipated swap out of the manifolds (simple thumb-push out and in), I cranked up the regulators to deliver 17 psi to the arm and settled in for a listening session that stretched into the wee hours of the morning and much of today.
To say that the HP manifold made a significant sonic improvement would be a colossal understatement. Each and every aspect of reproduction improved by a major step function. No need to specify micro/macro dynamics, impact of attack, clarity of decay, detail retrieval, low-frequency definition, warmth/richness, soundstage imaging/layering, space/air/transparency, or other descriptives. It simply improved them all and by a large margin. Night and day. REALISM!
Keep in mind that I had already recently upgraded the air supply system (Medo compressor, DIY surge tank, dual regulators, etc) and, while these were not revelatory until coupled with the HP manifold, surely all of those upgrades now contribute substantially to the overall result. I would be thrilled even had these upgrades cost 10 times what they actually did.
Many thanks to all of you on this thread, either by documenting these improvements here or by response to me directly, and especially to Frogman for providing advice, information, and the inspiration to achieve this elevated level of performance from my analog rig.
I am eager to rediscover the sound of my LP collection "as if for the first time".
