Line Stage Preamplifiers AX vs AU
Just learning a few things about these components,,, seems to me best tube fora linestage (PREamp term should only be applied to a amp with phono section/ w/o phone, = Line Stage) anyway,, seems to me best circuitty for a *passive line stage* would be the 12AU7 tube, and not employ any 12AX7's.
The AX ha s a mu of 100, so it really scrams and thus pushes the db level too much as it reaches the pwoer amp.
The AU has a mu of only 15, so its alsmost passive, which is really whata line stage should be , just passing the signal from the source to the amp, with the least involvement, IMHO alot of line stage amps, have too much coloration and muddiness due to the usage od 12AX7's.
Leaving me with voting the only line stage employing all 12AU7 circuitry i know of under $2K as best Line stage on the market.

CJ's newest line stage says **triod**, you would THINK, = A X or AU or AT,,no employs a single 6922, which might bea triod, i don't know,,, buta single 6922 ina line stage??? how is that tube , the glory of true tube circuitry? and then read the review, where the guy says, The real purpose ofa line stage is to pass the music, with the very least amount of influence/coloration** Yes, correct,,, But he also fails to complete the sentence,, **with the highest fidelity to the sonic fq;'s comming from the digital source,,** ahhh, thats the critical value of a ~true high fidelity line stage~~~ , passing fq with purity, naturalness, ~~FIDELITY~~( That ancient term Philips coined wayyy back at the very beginnings,, but which has gotten toss aside , lost among high powered selling ads, promos and such) Price? ha, get out your AMEX Gold card. https://conradjohnson.com/wp-content/uploads/2020/04/HiFi-182-conrad-johnson_HR.pdf |
~~$12K~~ for those curious on the price of the ET7S2. Hope I'm not stepping on any USA fans toes here,,,but come on, the Chinese engineers /lab has the USA lab beat by a grand slam,, In the shootout~~ would have Cayin smoking CJ's britches down before he even thought about drawing the gun.... soundstage, resolution, purirty, fidelity, dynamics, colors (Non coloration), musicality. One lab would rate high,,the other lab dismally low. |
Ck out the inners of the ET7 https://www.google.com/search?sxsrf=ALeKk000cEXXWHIR2WLzEcPIdr2LEC72Ww:1597803619764&source=univ&tbm=isch&q=conrad+johnson+et7s2+images&sa=X&ved=2ahUKEwj2kLSpmqbrAhVGI6wKHYlDAUsQsAR6BAgMEAE&biw=1280&bih=625#imgrc=IX4YdWXUnrLDbM&imgdii=bU510li4ZoQnoM Sorry I don't want my digital fq's passing through THAT mess. |
