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 ...

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...

[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...

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...

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...

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

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...

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...

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. ...

[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...

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...

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...

[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. ...

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...

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...

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...

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...

Hello,
I've just found out about the DS Audio's Optical Catridge which on their literature looks amazing but I have no means to sanely evaluate it from the technology point of view, and so I bring to the folks smart...
