ARC Ref 3: Tung-Sol 6550 in power supply?

This tube-rolling looks exciting.

Guido, could you direct me to a tube to "improve" my Rowland Continuum 500? I'm looking for, you know, some magic. ;-)

Use all your senses this time and give me a really good recommendation.

Dave

Hello again Guido- It's gratifying to see you validated my original post in so very short a time. KUDOS and happy listening!!

Thank you Rodman. As you know, I can only report what my ears tell me. And I try to report my observations in as descriptive manner as possible, so that other Audiogoners can draw their conclusions, based on my observations, not so much on my 'judgement'. And their conclusions are happily often opposite from myine. Terms better/worse are unfortunately not terribly useful in this business, being purely value judgements based on personal and too often unstated parameters. The only thing I can say at this point is that, between the factory supplied Winged C 6550 and the new production Tungsol 6550, I do prefer the Winged version for the musical reasons described in some details a few months ago. As for any other 6550 or KT88 version, I do not usually comment on devices I have no experience with. If some NOS 6550s or compatible serendipitously found their way into my system, I will report my observations accordingly.

Hi dave,
how about an early Jan 2008 NOS version of the TI Burr Brown OPA1632 differentially balanced OP amps in the linestage section?
I heard from a bunch of wild internet chipheads that it readily trounces the 2008 post march 31st current production. Best used after triple kryoing and slow warming up to room temperature in a tourmaline-based industrial drier. 77F Airflow with 45% humidity through a bed of crushed tourmaline minimizes residual Doppler effect by optical polirization of Oxigen 2O molecules. Current big issue is. . . what tourmaline variant to utilize: black Mexican, green (having the highest optical polarization index), or rose rubelite (being this last the most expensive jewelry grade variant, and therefore obviously the most desirable from a serious audiophyle point of view). The date of mining of the tourmaline may also have a considerable effect on the sound. . . Pre 1908 batches are the best, because they were extracted prior to the nepherious Tunguska event. . . provided you can find any. Hope this helps, G.

I agree Mr G- And I'll bet those "personal and unstated parameters" are too often one's familiarity with the real thing(live music). A subject that will get a post severly bashed in these forums. What a shame that we should take solace in those that disagree! I'm glad I've always considered myself simply a sound-tech/music lover and NEVER an "audiophile."
