I am with you on this one. I am also very suspicious of gigantic, 4-chassis phono stages if only because I just wonder why the need for all those damn noisy parts, along with concommitment connections?So it really pisses me off to admit that th...

Positive Feedback published David Robinson’s review of Lamm M1.2 amplifier.
http://www.positive-feedback.com/Issue34/lamm_1.2.htm
Frankly speaking I do have interest to see what people might say about Lamm M1.2. Not that I care about a review’s ob...

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...

Who has had success with active amplification of very low level signals (like LO MC output), apart from Boulder 2008 and super-expensive lab-type equipment?It seems like the safest path (that's still reasonably affordable) for LO MC lift-off is a (pa...

[quote user="Romy the Cat"]Let see what he have out there. I think the companies like Spectral, Boulder and Burmester are very much in position to make challenging contemporary preamps. In fact Burmester has been doing something like this for year bu...
|
|
Romy, I don't know from parts numbers, but there sure seems to be a world of difference between the stuff Guy and Boulder use versus everything else for audio out there. I have heard that some of the better op amps have two or three "tiers...
|
|
Cant really get why Lamm always underestimate the output impedance. A simple cathode follower would be of help and wont compromise the results. Boulder 1008 has 5ohm....

|
I suppose you have done the math on the input swamping, and/or you have run a simulation, and I suppose you know your amps sound OK with 6 dB more input. So, ask Guy if he will send it "on approval". I suppose it will be SS, discreet amps, or maybe...

[quote user="Romy the Cat"]So, my question to you guys: what techniques you use to filter out just wana-to-sound-intelligent audio people what you are engage in random let say phone conversation? Did you develop any practice to recognize that the per...
|
|
Well, I guess that about covers it, all right!But how do they get the 12AT7 input noise down 147 dB?!?They do mention something about using "quantum particle research", which might mean Bybee filters, or op amps, or both.So is this thing 2-stage ...

I am not a big fun of Dvorak 9th under Ancerl. I’m not big fun nether the orchestra’s balance nor the recording quality. Anyhow…
I do not think that that you need to worry PH-77’s accuracy of curves or the comfort to switch them. It looks lik...

Perhaps I should have mentioned before that the K&K is another spin-off of the well-received Arthur Loesch RIAA network. Also, the K&K's gain scheme is based on "classic" microphone circuits. While I am not say...

N-set, you've certainly earned the right to enjoy your gear! Again, which SUT will you use? No practical way to measure ESR, etc. on this, I suppose...When you first posted on the "problem" curve, I was thinking (to myself...) "RCL"/reactive load. ...

It can take me months to pan randomly through a given issue of Stereophile, but Fremer's review of the SS Vitus MO-P201 phonostage caught my attention this month.Mike actually clearly states that this 2-box item is better than the Boulder 2008. Well...

First order of business is to sell them at a high price; so, if their approach and their spiel seem familiar...Again, this sort of "balanced", "ultra-low-noise" circuitry has been around in the pro sound market for a while now, but NOT for phono stag...
|
|
Thank you for illustrating problems with the "approach". Now that your response has become part of the dialog, I remain hopeful to get some ideas for a "simple" phono stage that might not choke up on Bruckner or Wagner with battery power, and I do t...

Thanks Romy,I particularly appreciate the advice on the Goto issue, although a sojourn in Japan would be delightful too, come to think of it; in my experience there's no better place for culinary and audio tourism combined. "Local" support in the cas...

Value can exist at pretty much any price, yes. I should certainly have qualified all that with a "before Robert Parker came along", shouldn't I? He of course brings an added absurdity that hasn't (yet) infected audio reviewers, which is that damnable...

Last year I had the chance to listen to the Vitus SP-102 Phono Stage. When I remember right, it was ok, some of the better modern Phono Designs. It wasn't as thin and dead as Pass Phono for example, but it was also not able to go out of the way in re...
|
|
If you try/find an acceptable active MC step-up, please share your experience. I think the (stupid) Boulder op amp is the only one I've heard so far that does not sound severely "compressed" to me, and it really pisses me off that I have n...
|
|
Points about the self-sound of the PH-77 are well taken, not that I'll be spending 8K on anything any time soon, regardless of its "value".My own K&K phono stage is totally Spartan, just to avoid all the circuitry that typically facilitates the s...

Yes, Utopia was demoed in a large room. However:
1) Amplification: and yes, Boulder amplifiers were used. Good observation, but I don't understand why you think they would be a bad choice. I thought they quite complemented the Gra...
|
|
Romy,I merely thought that you felt I was riding roughshod over your advice, when it was in fact a degree of naivety requiring extensive clarification that may have made it appear thus. Regardless of your indifference to praise and/or criticism, I'd ...

Paul McGowan look like will be releasing soon PS Audio new devise NuWave Phono Converter. Read the release and see what it is. http://www.psaudio.com/shop/nuwave-phono-converter/ Unquestionably it is a very proper product, or I would say a family of ...

Rowuk, we do not disagree about the "battery/dynamics" equation. As you know, the "accepted notion" from the pundits is that "battery phono stages lack dynamics", and the one expensive unit I've heard did seem lethargic, albeit in a "salon". Howeve...

Retrofunk,Interesting observations. With regard to the speed variations with the flywheel, I have to wonder about your motor. I don't recognize particular unit. Do you have the original RY-5500 motor that came with the RX-5000? The RY-5500 has a buil...

[quote user="rowuk"]Hi Amir,your english is just fine.I think that there is an additional factor that your formula needs. Sense of pitch is not determined acoustically by "Q" unless we are talking about pure sine waves. When we add the overtones foun...

Last few days listening MiniMe with B-2 my patients was running out. With all more or less OK sound my B-2 had wondering eye about imaging. The amp has a minor fluctuation of gain between the channels and this fluctuation can be addressed by …kic...

It is shame that in 21 century we have such mediocre, not to say moronic, park of music servers.
Whoever does music servers t know stat a file server with uncompress 24-bit files is a phenomenal source of music. So, why we have not a lot of well-per...
