SONCOZ SGP1 Stereo Amplifier Review

[CleanSound]

I doubt it.

Well, manufacturer published spec is .07% from 20-20k, assuming at 8 ohm and at full power. It needs to be measured maybe, at some freq band, and power it might be better. Don't know, can't find any AP measurements for it.

Just don't get why this is "great" unless you think vu meters are the shiznit.

Not bad, far from SOA, but not bad and I'm still happy with it, even if it's not SOA.

If reliability and customer service (ownership experience unrelated to performance) is the number one factor in purchasing an amplifier, there is a price premium to be paid. Reliability alone does not tell the whole story because every electronic product has a failure rate - even if extraordinarily low, some poor buyer always loses this failure lottery and will get a dud, which is when customer service takes over and the product earns its price premium with longer warranty coverage, responsive customer support, prompt repairs or replacement, etc.

No argument, my question is about how to identify this - can it be built into reviews. @GXAlan provided some pointers. Still seems like each buyer must conduct their own due diligence with each purchase (sensible, but time consuming and inherently risky)

I'm not understanding the negativity about this product... it measures excellently, has decent power and looks great. Sure the price is a bit high, but performance wise there is nothing much to complain about at all.

I've got no issue with the "power of original sound" on the VU's in tiny letters... quite unique really.

+1 price is maybe high compared to some class-D offerings . But not for a good solid 100/200w 8/4ohm AB amplifier ?

I can live with the design, better than NAD battleship color scheme of old old QUAD amps also seemed to be painted in surplus battleship grey

You can like it or not, but Sonus Faber opened new vistas in the field of loudspeaker manufacturing with a never seen before design and wood craftsmanship.

A loudspeaker was an ugly box to hide, sonus faber made it something you are proud to show in your design living room.

Some of their speakers look nice (but so do other brands) but check out this $250,000 speaker:

This is what you say you would be proud to have in your living room???

 

[Mart68]

Tannoy were doing 'wood craftmanship' long before Sonus Faber was a twinkle in a dealer's eye. As were Castle Acoustics, Radford and a little later on, Ruark.

 

[Sokel]

I had the SF Olympica Nova III (in wenge) for some time (that's about 1/20th (street) price of the flagship Amir posted).
No photo can do justice of the quality feel they had.They just have that "something" .
But they were unfortunately small for my new space when we moved to our new house,so...

(I suspect they would not measure top notch too,even if they sounded ok to me)

Franco Serblin did a great job, but there is no question in my mind that the older Sonus Faber speakers were designed to a much higher aesthetic standard than today’s Sonus Faber. Compare the flagship @amirm posted above versus the old Franco Serblin era flagship.

I think the Sonus Faber line is an example of what went wrong with looks. The Soncoz measures well. It looks very good but it’s so close to being great in the looks department that everyone’s adding more thoughts for an update in Gen 2 cosmetics. Afterall, changing the typography isn’t very expensive.

It whose issue with Panasonic 2.1 HDMI chip which doesn't support full bandwidth specification. It's still the best performing AVR generation until smoke on the water (AKM factory fire) beside 4K hi variable FPS is still only a paper dream and at the time (cripto mining madness) it whosent even that much.

Doesn't change the fact there are several issues that are completely unacceptable. They released a product that wasn't up to standard just so they could get a new line of receivers out and sell them to unsuspecting consumers.

 

[ObjectiveSubjectivist]

Nice amp. I would consider it if I don't go fully active approach.

Anyway can someone explain me this:

Is it power supply leakage or distortion? As I'm not sure.

I didn't say there whosent and specifically I am saying there still is and don't worry they will soon came up with some new property standard so that they can sell you new one's even you won't have a big use of it. At the time that whose only available HDMI 2.1 turn key IP available, it whose rushed and not supporting full specifications so they could either use it and sell products or went to oblivion. Guess what they chose. 20+ year's back transparent DAC and DSP where more than accomplished thing (with emerge of Creative Audigy 2 PC sound cards that where 24 bit and with SINAD over 100 dB) and it whose wider available then it's today but we never gained end point open access to the DSP nor ability to use it as it matters the most to us (actually in this particular case it whose close to getting there with community driver's and DSP effects which just need more polishing). It's a closed cycle with ups and downs and constant but slow progress. If you think about it you almost constantly hear of such scamms and big corporation's reinventing hot water in order to charge you how they heated it up, it's a world we live in.

Intermodulation distortions. In this case f2 is 20 kHz and f1 is 19 kHz, which means f2-f1 is 1 kHz. The frequencies of those IMD components are f2-f1, 2(f2-f1), 3(f2-f1), etc.

Harmonic and Intermodulation Distortion

This post provides a quick comparison of how a distortion percentage relates to dynamic range in dB. That is, if an amplifier has 1% distortion, what does that mean? How soft (or loud) is 1%? Figure 1 shows a 1 kHz voltage signal with 1% second harmonic distortion (HD2) added. The spectral...

Thanks I'll read that.
I was aware that it's IMD distortion of two tones but I was not aware of how distortion products 'are calculated/showing'.
Anyway thanks for the link I'll definitely educate myself

This is an extreme concept, you should look at “normal” speakers. I own two sonus faber Cremona and I find them beautiful to the eye. Once again is always a metter of taste, there are no measurements for this.

 

[Labjr]

Would you power those Sonus Farber speakers with this Soncoz amp?

 

[CleanSound]

Would you power those Sonus Farber speakers with this Soncoz amp?

Why no? Ugly amp with an ugly speaker, perfect match. . .

Alright, alright. . .I'm sorry for being so immature, I saw an opening and I couldn't help myself. But it's all in good fun . . . apologies if I offended anyone.

And if you really got offended, let me know, I'll delete.

The Cremona’s are indeed beautiful but this gets to @amirm ‘s point. The Cremona is a Franco Serblin era Sonus Faber and you won’t find anything in the present lineup remotely as beautiful. This gets to the point that it isn’t about actual countries of origin but individual people.

The classic Cremona versus the contemporary Olympica
