Yes, Jonathan,
I have seen this resemblance with JBL in the shape of the back plate but it does not mean anything. The curved back magnetic path make a lot of sense, so he might adopt it from JBL. There is nothing wrong with it.
I do not k...

Paul,
I've been using my utterly boring pandemic free time to look for stuff on the internet and update the data/designs of some projects, and I am almost sure I've seen a company selling copper connectors (RCA at l...

Yep, Telstar. The 1547 was use in Sony and Teac CD players and believe the first CD-SACD machines used that chip. I know very little about those chips and have none of my personal experience to deal with all of it. The reasons why I brought it up bec...

Hi Roman, hi all...... very interesting topic... I recently made the contact between Josh and Klaus and his Goto system... I experienced Klaus' system three times and also if someway blaming his choices about using only and exclusively "liquid music"...

I don't know the full story of how loudspeakers went from field coils to permanent magnets. I believe that ultimately it was dictated by the price and availability of Alnico. Eventually Alnico became cheap enough to make similar or higher strength ma...

[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...

Four ML2.2s are used to bi-amp the Verity Audio speakers; I didn't know they could be daisy chained by using both the XLR and RC...

Thanks, Keith.
I isolated this topic in a separate thread, reading to the end you might understand why.
Those commentaries that something is “100% original” I usually take with a lot of suspicion and it usually is an indication that the peo...

It sounds that in your phonostage has to good (from electrical
perspective between you ground entry from PC to the unit and the main ground terminal
(presumably it would be the ground of your RCA). Some people feel that it
should be 4-6Ga terminal...

Hi Romy Reading your brief audio history really does not sound to different than the rest of us.So my next question is (how are you...

I tried a highly modded DEQX on my horns for some time, we did all the time alignment with it, we used 1st order and 4th order xovers and everything in between, we used LeCleach adjustment for bass and all the other drivers we had it sounding for som...

Thanks all for the replies! Looks like a very risky business.Given the work involved and highly unsure effect, I'll happily skip the shielding. Your comments suggest that the high capacitance line to ground (which the shield would happily provide) is...

[quote user="glaesemann"]I think we know why Purist does not send out refill kits. For the same reason HP and Canon do not send out ink refill kits. [/quote] You are incorrect. Diminus comes with lifetime warranty and Purist refill own cables for fre...

Interesting, at this stage it's early in your testing so I am mostly interested in how they are terminated. Can you provide a picture of how the fluid tubes are sealed and the cable terminated to RCA?

I have been rooting around looking for recordings and of course I scanned the "good BSO recordings" list. Charles Munch actually quit the BSO in early 1962, and I think I remember he died around the time I was married, 1968. I love h...

RCA stereo, LSC-2129, 1958I know it's popular in some circles to pick on the CSO. Well, pick on this.In this case, Reiner does a great job with a great orchestra. Heifetz is relaxed and in terrific form. His spectacular instrum...

Amir, here is a link to "the same" (same appearance, "specs" and information) SPDIF cable I got years ago (for maybe $200). It replaced the Belkin Synapse after the last round of "factory upgrades" to my iDAT DAC. Prior to those DAC "upgrades", I pr...

Hi,I've just taken receipt of a Model 2 to use as a DAC in my study (using the ADC occasionally for recording live from a mic). I would like to feed the balanced XLR outputs of the Model 2 into the single-ended RCA inputs of my Berning Siegfried amp,...
|
Thanks Romy, I'll try connecting with an XLR to RCA cable. I've actually ordered a Henry Matchbox HD also because I can use it elsewhere if it doesn't help in this particular case. In any event, I'm hoping to share some thoughts on the Model 2's ...
|
Yes, the layout kind of not optimum. You might try to lay the transformers sidewise and to make the RCA atop, above the transformers. Still, I hope you understand that your hum has very little to do with layout. Properly grounded unit shell has no no...

[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'm wondering if anyone used the industrial standard 2RM-type of connectors for a DIY Lo MC phono connection?http://www.trimmer.ru/?target=61&nom=20251The smallest is 2RM14 with 4 pins, 1mm dia so pretty low mass--no big diameter jump along the p...

I am all set with my reference arm but my dally arm with SME 3009/Otophone SPU Classic severely underperforms in my view. The arm use Otophone SPU Classic that is all together is OK balanced cartridge. Nothing overly exciting but more or less neu...

Well the thing is that the returning wave from the back side of the driver, does return in phase, but "later" than the front wave, logically. This should add some distortion that I have not noticed, but of course and worried for as much as I am worr...
|
Amir, the RCA vs. balanced can be a huge difference, depending on the application, and the longer the runs, the greater the difference. But I was talking about the materials and construction of available connectors, which are primarily made the way t...

Thanks, jtavan.
It was educational. I made some first steps already. I made a slow 233MHz (and presumable it would have lower noise with lower speed) machine with no fans, and a large passive radiator on SPU. Formatted it and loaded Win2K Pro St4. S...

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...
