Paul, I do not think that “before or after RIAA losses” requirement has any merit as no matter what kind type RIAA filter is being used it always will lose around 20dB. I do not think also that there is a “safest path” or “reasonably affordable”....

[quote user="Thorsten"] Well, a range of mono EQ curves (and only Mono) had turnovers other than 500Hz (AES with 400Hz comes to mind, often used by Rudy van Gelder and then there was Decca with a different turnover each year in the 1950's!). AMR's P...

Yes, first things first; playback should not be compromised for "features" (and I am the classic hair shirt guy). Here, I'm thinking that there's no need to spend this sort of money on a phonostage to get one that's good enough, and once we are spend...

[quote user="N-set"] Sorry Romy, I did not want to sound nitpicking. I'm rather trying to understand if my copy works +/- properly.[/quote] I do not see you nitpicking, you do the right things and I wools do the very same if I was at your place. 1V...

Todd, What you descried does not sound to me as inner-groove distortion, even though I am not exactly sure what inner-groove distortions are. The very first questing that I would ask if you have the same character of sound when you play your CD, or t...

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...

[quote user="deemon"]Brian , I never tried SSG cap in phonostage . SSG has a good reputation ..... but I'd prefer teflon for coupling . Mica caps , even good ones like SSG , seems too "bright" for me , but teflon sound pretty neut...

[quote user="difool"]What is the benefit of using 834PT in dual mono over a stereo 834PT? [/quote]
That is a good question and I asked myself it numerous times. My current standing is the benefits are purely intellectual as I am not able to observe ...

and I hope it will be up to the level … of FM in term of enjoyments. Anyhow, the phonostage is the already pack up in the chassis and running. I dropped the B+ supply to 270V and the R1 restore to 120K, keeping the 100V on the first plate. I can’t wa...

what you say is true, one might just as well start with the idea of a "minimal" phonostage that is powered by batteries. Naturally, if one has no clue what one wants with a "thing" then he is always essentially empty handed. Still, at some point on...

[quote user="Romy the Cat"]I did not say how my saga with APS Pure Power regenerator finish but it never finished. Since the end of the last year the regenerators is sitting in my closet and I have sent the unit’s main board to APS people for the “re...

How ironic that I finally got my phono running through the ML2s, and just as you say, it was not all it should be. In fact, I would have to say at this point that I am getting better sound from my crappy CD player, which I u...

Hi,[quote user="Genn"]May be it is time to review some basic concepts?[/quote]I am quite familiar with them, thank you.[quote]I'm using today IC based, Accu powered small amplifier, and it reproduces music, without any noise and distorsion from angry...

Yes, I understand Bud that anything might be done but I do not want any DIY solution. To deal with all of the shielding, with grounds… I do not want to be involved into all of it. Also, the transformer shall sit at the RCA exit jacks of phono cable. ...

Last night local guy stopped by to listen my last year changed in Audio. I proudly played to him a record on my “End of the Life Phonostage”… it sounded like crap. The electricity was not very good and I hardly was toleration when the record was over...

Come on, Thomas, no one talks about the 75-85db of gain at MM level. However, the higher gain does has some things that I find is very useful and I find it is much worth to burn extra 15dB in prams then to have a preamp wide open and run photo at low...

Yes, I guess I would sing the different songs if I need to load them differently. In fact Mi might need but I juts refuse to acknowledge it. Nevertheless I am not planning to compromise my phonostage by different loading. BTW, did you try to load the...

Yes, you are right, the voltage divider from 6.3V across 47K and 10K resistors shall give not 0.9V but 1.1V. However, the numbers that are in circuit are not something that I saw in my dreams but the actual numbers that I measured. I might presume th...

If anything, I have already laid out too much "background" or "context" including my likes, dislikes, whatever, at this long-suffering site. The idea here has nothing to do with anything other than getting "acceptable" sound more often than I do...

Hi Paul,My question was of cause about my phonostage based on EAR834p and "End Of Live" modification with air capacitors and LCLC + 0A2 power supply.A couple weeks before I increase the second stage ECC83 cathode capacitor value to 43400uF (Kaisei no...

Even though in the forum most of the thread stated as mockery of different companies, people and ideas but I would like to dilute this forum with a serious thread. The subject will be the Ayre Company.
I have to say that I never own any Ayre equipme...

Folks, This thread caught my attention, because here Romy waxes lyrically about the failings of the Denon Cartridges. Now I only consider ONE Denon worth bothering, the ORIGINAL 103, it is often inaccuratly called 103C. It has a medium compliance (ar...

Not long ago I made an online remrark about a deluxe/"flexible" phonostage, opining that I would rather have mm-only gain and fixed input R, since I use a SUT, and I don't want the extra circuitry idling in the background. The manufacturer responded...

KOTriode, I was not criticizing your DAC, whatever it is. I was saying that system-design-wise if your preamp was able to inflict such a dramatic change in Sound then in my view it just highlighted the problem with DAC. Take another DAC, or any comme...

[quote user="Paul S"]Romy, I am on the verge of an L-pad for my HF ribbons, but in my case I believe it is mostly the MC cartridge response I am wanting to offset, on a case by case basis. [/quote] Hm, this it VERY bad. Fix you cartridge setup, it's ...

Jarek,I would start at the beginning. Turn off and unplug the TT motor, remove the phono cable from the phonostage and use shorting plugs to short the inputs. This takes the TT/cart/arm/cable is out of the equation. Do you still have the humm? If...

Methinks that Mr C is correct in that the SPU cannot be deconstructed as I asked the same question elsewhere and got shouted down. :-( But hey, maybe they were minor league rookies and some major playa has the answer.... By the way ...

I am having a LOT of microphonic trouble with the 7788s in a high gain stage. I run a 40mV input signal into a 7788 triode at 15mA CCS. Plenty of gain, nicel output. But dang, if I bump the tube or board or chassis, the grids inside...
