One thing I have noticed a lot with gear that "aspires" is a ""rubber band" harmonic effect, with +/- higher or lower harmonics in preponderance as the dynamics/complexity changes. There is also the effect where the [am...

Yes, of course, agreed and point taken. I am/will be conscious (at times) of all those things as I listen, and I remain a musical omnivore. I am pleased, though, as I mentioned, because this is the first time I have had suc...

Romy, this whole report is just too interesting to wait for installments! I love it that you have found a way to "work with" the "effects" of the APS. But now I wonder about and I hope you will clearly address:Whether you use all com...

Roman,> Any IC-base RIAA corrector should cost $30, with no expiations.Now now.... My "Analogue Addicts Phono Stage" is Op-Amp based and requires at current OEM bugetary pricing in 1000pc lots of $12.25 each. Add Tinfoil & Polystyrene Capacito...

[quote user="Paul S"]I envy those who can use a scope like Tarot cards.[/quote]I for sure cannot, hoping you can. That's why I spammed the thread with the above noise "traces"[quote user="Paul S"]Will you mount initial gain tranny (or, not...) outsi...

I see the point, thanks a lot for your comments. Playing with the phono I've somehow come to a conlusion (possibly wrong) that my ham is an electrostatic air pick-up from the PS. During the operation both PS and signal boxes are very closetogether an...

Hi Romy,I am new to your site. I have read some of your postings (including other sites) with much gusto.For the digital LP recording, I am (was) tempted to do the same, but given the fact that I have absolutely no personal experience in digital audi...

The "lack" of HF is definitely one of the wonderful things that makes one think of spending 30K on a phono stage. Glad to hear you are "suffering" a similar "dirth" of HF [noise] with your DIY corrector.I wasn't going to say anything, but I won...

All the research and theory; all those exotic, expensive little bits and pieces; too bad there's no way to tell if a cartridge will work until you try it. And then there's precious little you can do to fix it if it doesn't.In plotting an end-around,...

Thanks for the tube gel sockets/absorbers hinting, Roman... Thomas had to use such a vibes taming mandatorily, being both 801 AND 437A tubes rather microphonic prone...Using his clever design... ZUT! Completely silent... also, unfortunately, he had t...

Yesterday I was more-or-less randomly reading Stereophile, skimming, in case something interesting to me appears, and Mr. Fremer in his Ortofon Verismo cartridge report told that top Ortofon cartridges use "6 nines" copper wire that has been gold pla...

Mats, believe me, I'd love to get off the frickin' grid altogether. But if I'm looking at >20 car batteries just for the K&K phono stage, then how many angels will fit on the head of a pin? Ironically, the K&K also uses JFETs.....

I lost all hope for horn loaded Lowther speakers . Got Phile Mikey (fremmer) recommended TT and new old MC cartrige (benz Mc3) so analong front sounds comparable to old modded MCintosh CD player I have. I finished (took al ong time ) Hagerman c...

First the other customers of PP that are having a hum problem are NOT my customers and use different components than I. Second it is not just the turntable motor but also get the hum from the phono stage when plugged in. Again plugging these componen...

Sounds "fun", Romy. I think the late (recently deceased) James Bongiorno contributed the lion's share of ideas for the Constellation, although who can ever be sure what actually makes it to market. Maybe Bongiorno's own (much cheaper) Spread Spectr...

OK, I just read most of the cartridge roll out. It turns out that the "reviewer" basically told the Big Dealer what he wanted from the cartridge maker. I guess the reviewer likes small winding, low output MCs ahead of time, so the manufacturer was ...

First as stated before, when I 1st received the unit no hum issue it was after it was sent back twice that it came about. 2nd if I use my other conditioner, a Purist Audio Design all is dead quite. The humming out of the speakers stops if you plug th...

In this cable thread there are some ideas about materials and construction of cables. My most recent attempt for good-sounding shielded phono cables are from Bud Purvine, using his specialty Litz wire construction, Vampire 800C connectors, and unblea...

Did you just answer your own question? Use the B2, then. Plenty of nice, small tube amps for tweeters, if that's what you want. I could list tube and SS amps, but I hate doing that "in public", not to mention, as you just pointed out, you only need t...

The Sussurro has an unusually wide loading range listed by Soundsmith, ranging from 470 ohms to 5k ohms. It is possible that more recent models have a somewhat tighter range between 470 and 2k ohms but I am not positive. The capacitance of Soundsmith...

N-set, by "traces" I meant the archaic(?) term for circuit. I envy those who can use a scope like Tarot cards.Will you mount initial gain tranny (or, not...) outside the phono stage box? I recommend it. Anyway, obviously, noise is much less of a pro...
|

Yes, it is anybody's guess how an active SS-only phono stage would sound with a low output MC, since this is usually a recipe for death (of Music). My own cartridge, for example, only puts out .125mV. I'm not so sure even the 2008 would work for my...
|
|
Of course I don't know if this also applies to your other cartridges that are working correctly through the same phono stage, but the VTA/bad electricity "problem" is peculiar to long line contact styluses. And as I also noted recently, po...

hi rony!sorry for the late reply, my job....i did not start to build the horn, working on a phono stage for a friend. will start to build the 60hz horn in about 2 months. all calculations are done, should be no problem. will be made of layers of plyw...

Just the symptoms caused by the bad electricity, tons of tubes and other parts in various stages of decline, pins/sockets/connections, along with analog and digital source issues is the stuff of madness. I am so happy when everything works...

Big differences between PS in my giant amps and my DAC, my passive attenuator and my phono stage, TT. PS has to be "good enough" for the application. Maybe "reverse engineered" from the demands end requirements (ie, the mind of the listener). Throw t...

Bud, you may have read some of my babblings about stacking ground planes and stray current attaching/backing up all over the place; it's a personal fetish. Not to mention the fact that getting the ground "stacked" correctly is almost impos...
|

Discussed many times on this site is the "dedicated ground" (aka "bleeder"), which generally includes a driven copper ground rod and a wire to it from the TT, arm, SUT, and/or phono stage. The idea is to get the resistance as low as possible, so the...

I just saw a post in memory of Kevin Carter, who passed away early February this year. I guess I was not the only person who enjoyed talking with him and doing audio business with him. I think quite a few people who visit this forum got Luhndal trans...

Thanks for the comments Romy. Would appreciate pointing out where the schematic is for the 7788 phono preamp or even better your friend´s 7788 mic preamp schematic. I can use the phono stage circuit minus the RIAA as a starter and th...
