N-set, the usual way of dialing in RIAA is the anti-RIAA curve, trying for null. This might be from any source with appropriate output voltage/impedance fed to the corrector input. The obvious problem with the LP is that it depends on the arm and c...

Perhaps some people thought I was kidding when I suggested using a mid-fi system to audition for SOTA phono cartridges... It took me almost 10 years to find a replacement for my old Sony CD player because, despite the fact that several I heard w...

Continuing my observation about the Timbres and Audio.From what I said above it is very important to understand that Timbres in Audio are not the photographic density of the colors themselves but rather an ability of a photograph to differentiate...

3 weeks, eh? Vs. how many years for functional DSET? Next, a great 5 cent cigar!Same questions about decoupling a phono stage from the split, re-setting the output impedance, and doubling the output. Where and exactly how does one split and boost the...

I recorded the output of my cartridge/ phono stage/ line stage with the stylus resting in a groove of a stationary record while playing a CD at high volume with heavy bass through another path. Since my system uses tubes I was also getting tube micro...

[quote user="Paul S"]Meanwhile: If you are going to use a SUT, this actually is a Big Deal that will profoundly affect the Sound you get from your system, regardless of which connectors or solder you use. I recommend you integrate the SUT (with its ...

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...

Hi Romy,I believe you're right and it's due to the amount of LF the vinyl outputs, which may be more than the Bidat or the tuner do. It doesn't happen with all the discs, just some of them, which happen to be old recordings that probably have mo...

Hi Guy, I know what you mean; this phono stage really should not work well at all. I mean, voltage doubler, 3 stages of 12ax7, feedback, cathode followers, garbage looking power supply shared tubes for stereo...mortifying isn't it! These ...

[quote user="anthony"]Have put all my DHT's on the curve tracer to see if pairs can be matched for preamp duties. [/quote] It was very interesting to read about all of it. If you have a socket for YO186 then you can accommodate all 4V tubes and I si...

Hi Romy,I feel very pleased for you. I was always somewhat puzzled by your descriptions of how you felt the S2 sounded, particularly between 600 and 1200 Hz. My experiences with a few different horns but always with a good quality SE amp were invaria...

I personally think Johnathan Carr is .....well.....yeah.I've owned turntables since I was 18. I've tried many cartridges, many phono preamps, and tried the "exotic" cabling, gold connectors, etc... and I've tried capacitance loading and resistive loa...

Tim, the cable loading is not what I meant. Purist does like higher current across the cable but which cable does not love it? Dave Clark described very well some of the aspect of usability of POD cables (like disturbance). Some of them he left out. ...

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...

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...

Rowuk, I like what you say, although who among us would not? Nevertheless the righteous immediacy of short-term auditions needn’t be dismissed.I can not however join you in your disparagement of what you’re pleased to call “voodoo” treatments. Just b...

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...

Well, as I understood it the strategy from the beginning was to use a number of specialized/optimized "channels" working together as opposed to the usual single amp or two amps for FR, and from your descriptions above it seems like you're getting wha...

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...

I wonder if you're doing your listening with the Bidat using its volume pot or you're using only vinyl with your phono correctors or maybe the ET-T-834 EAR using its volume pot. Maybe the Melquiades has its own attenuators. I'll be glad to know how y...

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...

TTH's ?By the way I've heard several 834's not just one. You are right though, I don't particularly care for what I feel is its rather obvious character.No ET magnetics either, hard to find/hear over here. I think a just handful were sold...

This post is the phono-relevant part of info carried over from my recent "better tubes" post in the ML2 thread.Subsequent listening has established that the electricity during that session was better than I'd thought at the time (dammit!). ...

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...
