Preamp Deal of the Century


If anyone is looking for a true "World Class" preamp at a very fair price..heed my advice. I just recieved a Supratek Syrah preamp that was hand built by Mick Maloney in Western Australia, and it is absolutely beautiful! This preamp is the best deal you will ever find. I would put it up against any preamp out there for both looks and sound. Price? $2500 for the Syrah (includes Killer Phono stage). Not into phono? Try the Chardonney line stage for $2100. Don't get me wrong, I am not associated with this company. I am just a very happy owner! This preamp is VERY dynamic, yet liquid. It conveys the sound of music better than any other preamp that I have ever heard! You can check out the Supratek website at www. cantech.net.au

Tom, nice post, thank you. Although I know what you mean by some posts on this site - most sites, actually - it is also true that many times a similar affliction is one of patronizing criticism without rationale, which, ironically, hypocritically, or at least in my book, is of a similar-in-kind offense as the one you cited. I do not think that citing an offense on the latter constitutes being "whacked." But enough of that...

I agree with you completely on your post, but with all the do-dads out there it sometimes takes a lot of experimentation to "see" the fluid thing. You can change a room a lot, but its best to let it breath. In the best of these types of rooms, some people initially call them live rooms, but as you said, its more than that, although, metaphorically, the room does seem more alive, as in organic, symmetrical in how sound "moves" (propagates/dissipates). The mind, on an existential level, is very sentitive to time/space incongruencies and a damped-type room can many times worsen things on that level while, on a level of perception that is less deep (where the mind is not listening as deep) some things may be perceived as improved. Which is why its tough to get a room right. Some rooms are well nigh impossible, but if you have a decent starting place you can have a room that is receptive, as in, one that allows energy to flow (its a vessel, as you say). Or rather, the room allows a simulcrum of the illusion of non-stereo produced music through a stereo instrument. The sound is not the same as heard in an orchestra, BUT the mind's perception of that musical event is catalyzed to similar depths of perception; the sound may be different, but the experience of the mind is similar (that's for you, Rcn...). A good, en-livened room can be a vessel for that message to be heard and experienced.

I remember I once visited the good men at Shun Mook at their homes in CA. The man who owned the company collected violins and when he placed a certain violin hanging by a thread centered in space behind the speakers, the dynamic/spatial nature of the room became a touch more "organic", continuous, etc. Even more strangely, he then put up a very rare and beautiful sounding violin in the same place and the room was utterly transformed, all the above traits seeming to be released and settled into each other, until all you did is fall back into the music and forget those traits at all; the mind was not cued to deep spatial incongruencies of sound movement and so you went deeper. It was an interesting experiment...

Has anyone rolled the regulator tubes (6L6EH's) that come with the Cortese ?

I was told that rolling the 2 regulators does not make much (if any) difference in the sound of the Cortese. Has anyone had great success in changing out the stock 6L6EH's and if so, what sonic changes did you hear and what tube yielded the best results ?

I have had some fantastic results with Neotron (NOS) 6SN7's and a GZ34 in place of the 2 6N6P's & the 5AR4 that Mick included. Both cost a fortune, but what difference. The sound is just spectacular. I loved my Cortese before the addition of these 3 new tubes and now it’s just beyond Heaven to sit down and listen.
Cello, glad you are happy with the pre and, yes, I do think the regulators make a difference. Mick told me he didn't think they would, but most people that own the pre, I would venture, would disagree. I have Tungsol brown-base 5881's in mine and like them quite well. The sound difference is not as dramatic as the 6SN7 sub, but it is of the same kind; once you have the PS rectifier and the 6SN7's about right, or just right like you seem to have, then you can hear it. The sound is more...relaxed, dynamics not quite as jumpy but more of an even rise time, although the scaling itself in terms of energy has not been changed. A bit like the dynamics of a good WE 300B, which ain't bad. Not quite that good, but in the same way. It was worth it; about $120 for a good matched NOS set off of ebay.

I balked at the regs too for a while, but bwhite talked me into it. He also has the Cortese (I have have Syrah) so his comments might be more relevant. Also, Ecclectique here says, with wisened ears, that the sin qua non is the WE350B's, which feels right, real right, to me, although I haven't heard them in the pre (very pricey). There's some talk about them above if you scan.

BTW, I'm not familiar with the Neotrons (Tungsol round plates marked that?)...
Asa, Thanks for your quick answer. - It's a big help.

Any clues on the best place to hunt up a pair of NOS WE350B's, WE 300VB's or Tungsol Brown Base 5881's ? If you were going to pick one of the group to start with, which one would you pick ?

I was told that the Neotron's are TungSol round plates. They are a French labeled product with the word Neotron & 6SN7 printed in red letters on the blackened glass. The base is black plastic like.
Hello Cello. Re: regulators in the supratek. They do indeed influence the sound of the pre,however...their influence is nowhere near the dramatic difference of the 6sn7 or the rectifier choice for that matter.I am using the syrah,not the cortese,however,I think the tube topology of the power supply is identical to both units, wherby the regulators are employed on the power supply chassis of the cortese along with the gz34.The syrah uses the regulators on the chassis of the pre and the rectifier is located on the seperate power supply.We have a large selection of different tubes and types that can be employed here for regulation duty.All of them being employed as a means of further smoothing the ripple of the rectifier.I believe this is why many believe that they have "no" influence on the sound of any given amplifier.The choice of rectifier and regulators can make a profound difference [as I am sure you heard when swapping out the stock 5ar4/gz34]. One can use an original NOS American [beam tetrodes] 6L6,G,GA,GB,GC, 5881, the obsenely expensive WE 350b and many others as well as their nos Euro equivalents like the el-34,el-37,Kt66,Kt-77 etc[read expensive again]. Most all of these tubes will sound a little different than the current modern equivalents like the eh 5881,russian or chineese 6L6's, kt-66 or el34's. I for one, cannot tolerate the russian KT-66,6L6,5881 as regulators in my rig, I do find the current chineese Kt-66 the most relaxed sounding of any of the modern made equivalents.All nos 6L6 will better "any" of the modern equivalents with the possible execption of the original nos 6L6 [metal] which... in my rig sounds very similiar to the sovteks. The tung sol 5881 is the tube of choice here, however the old 6L6g [ST-bottle shaped version only] is also a very nice choice and can be found for typically 20% of the cost of the tung-sols.Regulators will not influence frequency or tone like that of the 6sn7 tube types.Their impact or influence has more to do with air and spatial cues in a sublimal sense.A sound that is more relaxed and effortless in a musical way. Allowing one to hear very fine micro detail, nuance and subtle spatial cues that are burried in the texture of the music.This hidden imformation is definitively masked when the stock tubes are used...This hidden imformation or nuance per say is very clearly resolved ,its just simply "there" and coherent in a natural kind of way with out requiring one to concentrate in order to hear these artifacts in the recording. It seems to pull you in closer to the music and forget about your equipment.Really very obvious when one puts the stock tubes back in.The genelec kt-66 or mullard el 37 are probably the best of all of the types I have listed here and will get you very close to the greatest beamed power tube ever produced, The Western Electric 350b. A side note here for supratek owners... There is another nos tube that I am currently employing for regulation duty in the syrah that I honestly believe can hold its own with the esteemed WE 350b! The best of it is...they can be had for pennies. I will post my thoughts here after I have climatized myself with this particular tube.
