Omni Gon The Final Phonostage

[Reinhard]

A few details - the easy stuff ..:

Phono specs for OmniGon s/n 10 (ALF's):
RIAA accuracy (20 Hz to 20 kHz): better than +/- 0.1 dB.
Phono linear phase derivation (DLP) 20 Hz to 20 kHz phono MM: less than + 0.2°
Phono linear phase derivation (DLP) 20 Hz to 20 kHz phono MC (3-6 Ohms): less than + 1.5 °
Frequency response Phono MC1: -3 dB at 0.4 Hz and 210 kHz
Phono Overload MM: 400 mV
Phono Overload MC 1: 38 mV
Phono MM IMD RIAA de-emp. 20 Hz to 20 kHz: less than 0.019%
Phono MM THD RIAA de-emp. 20 Hz to 20 kHz: less than 0.02%
Phono MC1 IMD RIAA de-emp. 20 Hz to 20 kHz: less than 0.03%
Phono MC1 THD RIAA de-emp. 20 Hz to 20 kHz: less than 0.03%
Channel separation Phono: 92 dB
Output impedance: 120 Ohms
Tube complement: VT229 (2x), VT231 (2x), E80cc (4x), CV135 (4x)

And .... Lundahl cokes only inside power supply .... Syntax' pictures do only show the part of the iceberg which is above water line ...

Good morning,

signal/noise is part of the easy stuff.

To make us happy please show us some pictures from under the water line,

Regards,

Reinhard

I guess, it's not a quote, just my remark. Maybe I don't understand your question?

Oh, no big deal at all; you said that $33,500 was a good deal for the well 'calibrated' people.

And then later on you made an allusion to the German Mafia, isn't it? Lol

I simply found it funny in my own way that's all. Totally innocent and pleasurable to read.

Most important, does it have a "Soul"....ijijijiiji

It will sound like crap unless you use 40k cables!

Kidding aside, it looks just wonderful I guess it will be very hard to come by on Agon again.... Overkill is always good!

Do you have some mroe details about the preamp, Does it use a SUT? all tubes?

 

[DDB]

And I won't hold it against the unit that it has cathode follower output stages (120 ohm output impedance)

However, how about signal to noise....not going to be as impresssive as a whole slew of phono stages out there, but I will grant you that noise is not bad as long as it is low enough to be non-intrusive.

Got Noise?

Tom

It is not a cathode follower output stage ....

The signal to noise depends on the tubes - 82 to 88 dB/1 V output / unweighted.

I believe that your question is, "does it have a Soul?

Well, it is a full-function preamplifier and to anthropomorphize its characteristics here is simply an artifact of this audio virus. However, those tubes do put off a some heat, not much, and can bring forth a little light when it is dark, the mains are clean, and the air is clear...bringing a little life into the container.

I do believe that the Omni Gon does that better than the other full-function preamplifiers that I have had as a conduit feeding the audio chain in my room.

All tubes - all triode - up to 4 pairs SUT.
The one mentioned and offered by ALF does feature 4 different MC inputs (each which it's own SUT) and 1 MM phono input.
An unique passive RIAA phono EQ.
All hard wired point-to-point.
Each tubes has it's own tube heater supply.

Think he is using a TVC driven balanced with E80CC,

Well, that is indeed a interesting question (beside from those who want some technical info for their own education)


Hm, all I can say, it makes audiophile life definitely really interesting...

 

[Reinhard]

(beside from those who want some technical info for their own education)

It would be better to educate the guys building that amp how to handle a solder iron or keep the cases closed.

Others can be educated in counting rectifier tubes,

Reinhard

 

[Reinhard]

thanks. BTW, as a kid I lived in west germany, 1966-68. Fun time and had some great german friends. Village of Pruem.

Tom

Think your dad was in the army, radar station?

You are Jonny English, right?
Always close like a Shadow but when your moment is coming, you press always - for 100% - the wrong button.
(And there are so many...)

 

[Reinhard]

(8 single-wave rectifiers - 4 each channel)

here are the facts, Mr. English.

Only for the records: Johnny

 

[NorthStar]

Awesome internals!

 

[Reinhard]

In the thread opening we find "full symmetrical" and on the amplifier faceplate "full differential balanced".
But there is not a single balanced interface. Only RCA´s and even the XLR´s are only connected pin 2.
One XLR pair is not connected at all.
Can someone explain that? Please only answers with electronic skill.

DDB or Daniel or Dietrick or his other alias -- sucks you in and then de-frauds you

I prepaid for an Omnigon in 2011 and was given excuse after excuse for non-delivery. I was silly and believed them. When it was finally delivered, i found that many others around have had delays of up to 2 years after they have paid him, and that many people never get their money back.

I also paid 8,000 for his 8x8 amps with the written promise that upon audition, if not liked, could return for full refund. He delivered them in december 2012. i listen a couple of days and rejected them just as Syntax , i later found out, had done. Daniel, alias lots of names, took the amps and has never paid me the money....... And this is only part of the story. I cancelled other things like a silver coil and instead took a copper coil in a xover he was building for me. +5000$ but he will not give me back my money. reason? None. He just ignores my mail and phone calls. .....The story is endless of his defrauding people.

Since my experience i am connecting with many others with the same experience. I am filing charges with the District attorney of fraud and international wiretape fraud which is a felony in my state.

The story is endless of his deception and fraud. beware.

 

[rockitman]

An overpriced Heath Kit ? That sux. "full differential balanced" with RCA's ???...that's a new one. Sorry for your troubles CSL. Syntax praises The OmyGodigon as the best thing since sliced bread...all other's need not apply.

I have had some private emails regarding mine and Mr. L's situation; I want to be patently
clear that Syntax is in NO way connected with our business dealings with Axinia Schaefer or Dietrich "Dertonarm" Brakemeier.

Syntax is a friend and a fellow audiophile that has a driven passion for finding what is possible in our hobby and sharing his solutions with his postings.

Sorry to read such, reading your statement above you might want to edit when you wrote "he delivered them in december 2012" did you mean 2011 because it's currently April 2012 so that date isn't making sense.

Can you clarify exactly how much out of pocket you are because reading it appears $8,000.00 for the amps but then makes referrence to + $5,000.00 for a coil etc.

What country are you located in?

DDB these are some VERY serious accusations, you really need to comment and provide your side.

 

[CSL]

in my post not saying syntax connected, only that he returned the 8x8 just as i did.

for DEV post below......17,000 for prepayment on Apolyt, silver coil in xover cancelled and he instead used copper coils but never repaid the $,
and various other things.

Great S/N as well!

Tom

Dear Tomelex: Any phono stage can " shine " at 1mv and where is not refered to any know standards. Things could be different and with real meaning if that spec was refered example: MC stage refered to 0.5mv. and according the standard/norm/rule: EIA/CEA-490-A , IMHO that s/n specs means almost nothing as almost all the other specs on that item.

Btw, how can any one that is proudly of his design to write that spec on the RIAA accuracy?: " better than 0.1db ". Why better and not the right value the precise one? because the measurement tools that he use it can't do it? why then?

In the other side, as important is the precise RIAA deviation value/measure as important is to know wich is the RIAA deviation for each channel and if that is maintened under any cirmcustances and through the time.

I can go on with all those specs but is useless when there is no references on standards and on each single channel.

A different subject could be that the manufacturer came here and show us a chart/diagram of those two channels RIAA frequency response measured through an Audio Precision System Two device inside a standard reference. Because numbers are only that if not related to standard references.


Do you want to know a true differential, zero feedback, direct coupled and no SUTs ( that always degrade the signal ) tube phono stage with IMHO more real engennering and nothing to " hide " ?:

IMHO not all what shines is always gold!. Well, Syntax said is gold ?????
