Opinons on Musical Fidelity A3 cr Preamp


Very interesting preamp so far (I've had it 3 days). Doesn't sound like a solid-state preamp at all. Very musical, very natural, relaxed sound. Harmonically complex, especially in comparison to my MFA Magus tube preamp - which has a sweet, forward midrange, but not that much on either the top or the bottom). A little less bright than the Magus as well, and I'm find myself having to raise the volume a little higher with the MF to hear vocalists than with the Magus -- probably because the tube units pronounced midrange emphasis. After 8 years with the Magus, it's taking a little getting used to. The MF is far superior with classical recordings. I am leaning towards keeping it (I have the usual 30 day return privledge with Audio Advisor), but I'd be interested other owners/previous auditioner's opinions. If it goes back, I'd probably be looking for a pre-owned Joule Electra LM-100 III (at probably $600 more than the MF) or Rogue Audio 99 -- pieces (from what I've read) are worth a serious audition. So I'd be interested in any comparisons to those units.

It's somewhat difficult to quantify how much better any one product is over another. Does the retubed Line 1 stomp all over the A3cr? Absolutely not, and the MF has some very desirable strengths, including razor sharp but smooth full spectrum resolution and no need to find and buy rather expensive NOS tubes down the line. But as I mentioned previously, I think with the right tubes the SF yields an overall realism that the MF doesn't quite match. It's very close, however, and I would happily live with the MF if I had to. The SF with the Siemens just gives a greater sense of holographic "thereness" than the MF, without any loss of detail or extension. Dare I say, but it was the slightest bit more musical than the A3, at least in my setup. Please also note that it takes a VERY long time to burn in a SF pre amp, especially when you notice all those Multicaps inside (I've used Multicaps in prior tube projects and they take literally hundreds of hours to settle down, during which they sound very brittle). Only having the SF a couple of weeks may not have been long enough for a decent burn in. There are some other factors besides the sound that had me more impressed with the SF, including the extensive use of much better quality components, better rear jack layout (the MF has a rough time accomodating larger RCA pairs), and more usable features, such as non degrading balance control. SF also does offer upgrades to their products (such as the SE version you mentioned - and Valvos are very nice tubes), which MF does not. Contrary to some posts, I've had no problems with my SF and it has a higher quality "feel" to it than the MF, if that is important to you. If might be impossible to do, but before you give up on the A3 perhaps an SF dealer would loan you a demo Line 1 with upgraded tubes (many SF dealers sell NOS tubes) to compare directly in your system. That is really the only sure way to tell. One last note: you mentioned an interest in the Joule. It should be noted that Joule pre amps are designed, voiced and manufactured with carefully selected NOS tube makes (Jud Barber is a big believer in the superiority of NOS) - perhaps explaining their wonderous performance. I can only imagine what an LA-100 would sound like with new Sovteks.
i haven't tried either the s/f *or* the m/f, but, i recently went from solid-state to tubes. i was using the latest iteration of the linn kairn, which was wery nice - accurate, detailed, dynamic, extended, good soundstage width & height - but it lacked depth. i hoped tubes would give this to me, but i dint wanna lose what the linn was good at.

1st, i tried a rogue *magnum* version of the 99, & it definitely did the depth thing! but, i lost a lot at the frequency extremes, especially the dynamics, range & texture in the bass. i tried nos tubes, which helped, but i couldn't live w/it. also seemed a bit coloured thruout the range, but i prolly wooda kept it if it got the bass right. in fairness, there may have been an impedence mismatch - rogue sez the output impedence is 100 ohms, but, after crosing the outputs w/resistors, my guess is 2400 ohms is closer.

next, i tried a cary slp98l. this was better in all aspects - not as coloured, and as extended in the bass as my linn. everything i wanted in a preamp! and, the wersion i tried dint have any of the upgrade caps cary offers. mite be even betteer w/them.

but, just days after buying the cary, i came across a melos music director (latest version of their ma333). i just *had* to try it, remembering how much i liked the sha-gold, the model below, a few years before. well, nice as the cary is, the melos is in another league altogether. sounds like *music*! :>)

i was able to try all this stuff, cuz i bought either used or demo - the only way to do it, unless yure loaded, or yer local dealer will lend ya everything ya wanna try.

the cary, a nice preamp, is definitely in your budget, if bought used, but the melos, (or something else in its price-range, used), isn't much more, & will take you to another level, imho.

Well, it has been two weeks with the Musical Fidelity -- and I must say I am extremely impressed. It is a terrific unit (as least as far as I can tell, since I will never use the phono stage) that seems more and more musical every day. My only serious quibble is the meagre range of the remote (which is limited to about 15 feet, at least 5-8 less than my $250 Pioneer DVD-525 transport!) -- which I will eventually try to remedy by writing Mr. Michelson personally. Other than that, I can't imagine a solid state unit sounding any sweeter or more musical (at least within any vaguely sensible price range). I will almost assuredly keep it -- and add 1 or 2 of the matching amps at some point (to replace my Conrad Johnson MF-200). My guess is that a third-party line cord will further improve the musicality of the unit (the supplied cord is exceedingly thin and generic), as well as eventually running the preamp from a PS Audio Powerplant. Thanks everyone for your input. Opinions on the matching amp are also appreciated (although I may indeed eventually need two to drive Apogee Duetta Signatures).
horizon, for that remote problem, ewe can buy an infra-red remote range extender from rat-shack for ~$50. mcm electronics had a similar panasonic wersion on-sale for ~$26 bucks..
