This is always good advice, to get to know the character of the phono stage. Because my favorite cartridges are not low voltage (I use Decca London Jubilee and Reference) I have never had a need for the ET SU-1 step up unit. In fact, I had this in my...

Sounds too good to be true, Romy. But it is winter, and I admit I'm still holding my breath.From the reports so far, it looks like the thing might be worked with to good overall advantage; but, as usual, some significant adaptation is...
|
I had my best-to-date listening sessions this year, but still 2008 has been a mixed bag for me. I did get pretty much what I was aiming for, or rather I did on those occasions when the electricity happened to be decent....
|
then the idea of amp bypassing is relevant to the "clean signal" discussion. But regardless of the measured voltage out vs. driver sensitivity I suspect that there is too little of something in the way of drive and control between a&n...

I feel that the correct objective of home music listening should be to reproduce as closely as possible what one can enjoy in a great concert hall with great musicians.Thus, I have been a advocate for surround processing for years. As stereo replaced...
|
I am with you on this one. I am also very suspicious of gigantic, 4-chassis phono stages if only because I just wonder why the need for all those damn noisy parts, along with concommitment connections?So it really pisses me off to admit that th...

Hi Romy, I don't doubt for a moment that there are plenty of people 'who know' who will wax lyrical about the benefits of open loop eq in feedback circuits. There are people 'who know' who will tell me that valve amplifiers cannot be as good as trans...

Hey Mr M, phono stage will be quite a while yet. I'm way behind on my commissions for various unfortunate reasons :(
Did I tell you I got my own cool Dragon Stockholm vinyl?
Um, probably...

Romy, my experience with the Lundahl amorphous core transformenrs is limited to my new phono stage, and I have have been dealing other issues enough that I am not ready to write much about it yet.Still, there are qualities worth noting...

[quote user="Romy the Cat"]Be advised that any pro-computer playback in this there will be objected...[/quote]OK, I'll bear this in mind...I think computer playback is fraught with issues. Even a simple thing like the type of hard-drive used affects ...

You might think I'd learn by now, but over the last two days I have traced sonic problems to the following: Dirty pins on one of the tubes in my phono stage; Loose counterweight set screw/too-heavy VTF; Loose cartridge mounting screw/...
|
Sorry, Adrian, I did not hear either phono stage in my present system, nor did I A/B them, but I "compared" them in my "aural memory", with the actual listening sessions spaced several years apart. Back around the time of the FET 10, maybe a li...
|
Well, that sounds perfectly reasonable, and it also gives you an out in case you happen to hear something else that really turns your head.Although 2007 did not make it appear so, I have had +/- the same thoughts about gear for some time, perhap...
|
It has been 1 year since I started working with the ML2s with all new tubes installed. The ML2s have been, by far, the biggest step I have taken in hi-fi in 45 years, and the "upgrades" I have done since the ML2s have necessarily been in a...
|
In impatient, ill-advised. manic efforts to "compensate" for the EFFECTS of bad power I have swapped ICs, used different output taps, re-configured grounds, swapped tubes, re-positioned speakers, adjusted VTA, messed with my BR ports. And ...
|
***The proper loading value is difficult to say without knowing your system, as it is partly a preamp and ultrasonic RF issue as well as one that involves the cartridge and audible frequencies. Some cartridges have frequency abberations within ...
|
[quote user="twogoodears"] Yes Roman... I feel pretty like I entered a sort of "cul de sac", tube-wise... I contacted, few months ago, Western Electric USA and they told me that, at USD 750 ea. they have "plenty" of N.O.S. WE 437A... I've been ab...

[quote user="hagtech"]My Stu never got a reply by the asylum inmates. Maybe nobody there ever heard of a 7788. No help.[/quote]7788, gain/noise/bias vise, as a penthod, is pretty much idle first stage for not-extra-stages low input preamp...
|
It took some work, but I finally got a new phono stage (K&K) and a Bent TAP (transformer-based volume control) installed, along with some new cartridge clips (ugh!), and I put the "new system" through its paces Saturday and Sunday. I a...
|
Trying to gather and get my thoughts in order, in order to share them, I just remembered a recent mod that John Wright happened to mention specifically. While I believe John regards - and guards - as proprietary his ideas for reworking this gear, I a...
|
It seems like lots of folks use parts to try to tune/voice their systems, and the V-Caps are just another option, IMO. No matter what people think of new parts as they break them in, they will eventually tire of the overall sound from...
|
Hi Romy, I recently heard the smallest Cessaro and while I felt that the bass was not adequate for long term satisfaction it was also not a total disaster. From the midbass on up; however, the speaker is simply superb and one of the very best h...
|
John, it is interesting that you qualified application by the base metal used in the transformer. Here at GSC, many use "exotic" and/or "amorphous" cores, or perhaps high nickel content (or Si) for chokes. As it happens my own phono stage uses exot...

first post... but I recognize quite a few friends here.. so, my straight horns... I like them very much.. I built mine similar in style to what Greg B linked, but obviously much smaller.. mine are just under eight feet long (length of a sheet&nb...
|
[quote user="hagtech"]Ah, think of it this way. Imagine floating the input to your ET step-ups. Don't ground it. Let the primary and phono cartridge float. This is a similar situation but far far more sensitive. It's a m...

[quote user="SOS "]First the other customers of PP that are having a hum problem are NOT my customers and use different components than I. Second it is not just the turntable motor but also get the hum from the phono stage when plugged in. Again plug...
|
[quote user="Paul S"] At the same time, I am wondering about what sources you have been using. I mentioned early on that the Jubilee is polite, and I wonder what the Shelter might sound like with the "softer power", just with respect to a capac...

Recently I was visiting a guy who has Alnic H-1500 LCR Phono stage. I actually had a chance to open it up and to inspect it.

I thought about this for many years... but, to make the story short:I agree with that idea for Loudspeaker manufactures, this makes a bit sense, but even here you will have experiences, which will make you die 10 years earlier.Avant-Garde for example...

[quote user="guy sergeant"] It's polishing a turd though isn't it? I listened to the 834 quite a bit when it came out and thought it sounded poor, even for the price. imho, The circuit's just bad. If you do all that to it it isn't really an 834 anywa...
