[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 ...

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...

I wanted to compare a LP pressed at 33 1/3 and 45 RPM of the same music..To listen for any pinched effect or inner groove compression & distortion..Two identicle turntables and arms plus switching at phono preamp gave me the tool needed for this ...

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...

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...

Since my First, “End of Life" Phonostage will be done soon ( my mechanism has been doing the box for 3 month)

I think again what will be the Second Phonostage to care my other arms...

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...

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...

[quote user="Romy the Cat"]The real wet dream of mine, something that I would like to have but never went for is to have in the axis of the air caps a high precision step motor and a remote control that would allow me to modify the phono equalization...

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. ...

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 ...

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...

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...

[quote user="Paul S"] I would like to hear something more rigorous and complex than "the usual" music the DIYers use to "prove" a design/system.[/quote]Was my thought too--"a girl with a banjo" audiopedophile(tm) crap.[quote user="Paul S"]Unusual TT!...

Yes, 10 uF is rather large for a coupler, alright, but not unheard of. Conversely, .47uF would be on the small side for a "powerful" amp using the 6C33C out (4.7 uF might be more like it...). My own phono stage uses 5 uF film couplers. One would supp...

[quote user="coops"]Romy Hi, Ralph installs every pair of speakers ,I know that it can take a week or more to install and optimise the larger systems. There are plans for amplifcation , he is working closely with Mr Park of Allnic Audio. M...

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...
|

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...

[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...

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. ...

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...

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...

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...

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...

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...

Yes, well...VERY hot today and power was changing from good to stinking bad and back over a span of minutes, sound pumping away like a ghoulish accordian.I used the opportunity to re-set my arm damping for the 16 Ohm taps on the ML2s, assuming I coul...

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...
