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 ...

Well, maybe a little cussing first to set the tone. The older SPU's are now well sought after, many will end up in collections at now over inflated prices probably in the Far-East where they are worshipped. I've heard a few older SPU's and even those...

I have seen people use 12AU7, 12AT7, the circuitry might be tweaked and it will accept anything. I use a 7025 in second stage (look into the linked thread “Once more unto the phonostage dear friend!”). Hey, I even used a transistor as follower! I kno...

I got home. I turned the thing on, I played it and it was just unjustly compressed. I demagnetized it, it got better, even though the cartridge did not pay a lot since I demagnetized it last time. It is still not where I would like it to be. It is ju...

Rony,
Actually I did try to drive Melquiades from different source. My old tube buffer, my phonostage and any other not DC-coupled source were not able to drive it. The 6-ch Melquiades is pain in as to drive. It has around 5K input impedance ...

Hi,[quote user="dazzdax"]Thx for this well written and highly educational piece Thorsten! It appears that Romy is not very fond of the Audio Consulting transformers, could you give your opinion regarding those? What is your opinion regarding the use ...

This year is the first winter that I live with this new listening room. Last winter the playback was up and I still was playing with minor arrangements of my ULF channels, cable and a few other things. For many months I do pretty much nothing with my...

The very much non-definitive EAR 834P Modification Guide by Loesch Thorsten
Hi,Given that Romy already let the proverbial Cat out of the Bag (pun intended) I think I may have to make good here....
The EAR 834P is a very simple, but rather smartly ...

[quote user="Stitch"] I agree, the Shelter transformer is nothing special, but when you really want to loose hairs, try the one from Koetsu. Well, living in a world of morons I spend - unfortunately - too much time with reading idiotic reviews fr...

[quote user="joaco"]Hello all , i know this topic is almost about pp experience but since im experimenting with electricity i like to share some thoughts here . I builded a dac using very high quality components . As you know the power supply is crit...
|
Yes, Jim, you put it very well. Still in case of the 6C33C it only possible to cool the glass and I made experiments blowing a strong flow to the glass and it did cool down the plates. The problem is that it is not a good idea to apply a strong flow ...

Funny, funny but those 2 47uf capacitors are the only eminent the worth to keep in this kit – they looks like very good polypropylene caps. I also a person who go uselessly go for chokes with high DCR not lover. Anyhow, I am not changing any magnetic...

[quote user="Romy the Cat"]FM Acoustics’s Manuel
Humber speaks about his Harmonic Linearizer device. It is very possible that this FM Acoustics preamp is a fine
unit and that it does better than other EQ solutions but why the EQ solution

[quote user="rowuk"]How many sources do you currently have? If you are building a phono corrector, make it for 4 volts output. If you have a PC for digital playback, there are good DACs with more than 2V output. That would leave a tuner to pimp - cer...

[quote user="Romy the Cat"]I have to admit that some of my opponents might consider my organizational views on high-end audio too socialistic and will recognize in my view some residues of me growing up in socialistic society. Leaving aside the preju...

[quote user="Romy the Cat"]
How difficult is it to find 437As good enough for a phonostage? For commercial applications is it a dead tube. WE might produce it again when they stated to redo the tubes but the existence of the Russian 6C45P pretty mu...

Here is a Thai guy looks like built my “End of Life Phonostage”

I do not see nether input choke or air capacitors in correction chain. The most important I have no idea what step-up transformer he us...

[quote user="Brian Clark"] My stereo corrector (834P with air-vane caps) has a shorting switch across the two channels at the input. I suggest you incorporate the same.With it out of circuit I did indeed get that hum you refer to with the SPU Mono. S...

It has been changed. Looking at the extend of my record collection, the efforts I went with my TT setup and my “End of the Life Phonostage” it would be hardly expected from me to be somebody else a die-hard vinyl dude but it is what it is. Those feel...

Alex,
I am sorry, I know very little about Benz cartridges but I was wondering what heck you do for living that you are able 6 hours a day spin records while you in the office. Are you getting paid for listening and changing the records? Or ar...

I started in hi-fi with LPs and I have never stopped using them as my principal source for hi-fi. Some time ago I decided that master tape was better than vinyl, but I could not afford to go that route; so I settled on the next best thing: a cartrid...
|
Your Pass at it’s MM input should have adjustable capacitate. Drive it all the way down – the ER does not want to see any capacitance and for MC cartridge it is not necessary. I know what you mean but that “SU1 sound you cannotdescribe” – it is like ...

Just a few lines to the "Performance" of this piece of wood on strings for 7k $I listened to the Schroeder Reference + SQ and some custom made ones which were normally not available (Schroeder model blahblah with Valhalla cable etc.)(of course you ca...

[quote user="floobydust"] By definition and code, a separate non-current carrying ground is required for all outlets. In every house I've lived in, the ground is a separate thick copper bar that goes deep into the ground (the earth outside the house)...

Actually I use Koussevitzky 1949 version of Tchaikovsky’s IV (first movement) to assess my mono analog. There is not doubts in my mind that any more or less serious records enthuses much have a dedicated mono cartridge, preferably permanently install...
|
Guy,I absolutely disagree and I think there is a huge difference between lettings your wife to know that skin in her neck remind you sesame chicken and letting a play director know that his new production stinks. Of course we moderate our behavior in...

In a way you can write some positive / negative about nearly every Design out there. The Micro 5000 & 8000 are 20 years old, they have 2 weak features- a Platter which rings- no suspensionBUT, when we look at their latest units, we can see that M...

Last week I had a date with my Psychotherapist (every serious Audiophile needs one when he is above 40 and Al - his name is Al Right - charges only 165$/h, he is an Audiophile and a good guy. In his waiting room I met my old buddy De - his name i...

Ok, looking at the flawless performance of my PP2000 I decided to get the PP3000, which was ordered today:

As I turn my entire playback on (phonostage and Pacific) I suck 96% from PP200...
