JL ELectronics Sylph-D200 Amplifier Module Review

Nice power supply. And Topping did take note I guess with the PA5.
Got the Burson Audio V5i after I tested the V6 Vivid.
I think this is one of the best opamp for Sylph-D200 in terms of overall presentation. I find it miles better than the V6 vivid, maybe because I like the 'opamp' sound better than 'discrete' buffer sound.
It is also smoother sounding than the TPA3255 user's favorite which is the OPA1656. It is more pleasant sounding and doesn't have the 'thin' or 'compressed' upper midrange sound of the OPA1656. Though OPA1656 has a noticeably 'rounder' and 'fuller' vocals.

Meanwell LRS-350-36 (or 48) is also good if you have a chassis with lots of space to put it.
Does not affect the THD+N performance of Sylph-D200 module when I tested it. Doesn't degrade the sound (still superb) and is very cheap, just avoid buying fake and get it directly from Mouser or Digikey.
Meanwell 350-48 is what I used with an eval board cased up. Works great.
Nice. They certainly look the part! Would you say it's worth the investment for use in the Sylph-D200? Certainly not a cheap op-amp...depending on where one buys them the cost is nearly as high as the amp module itself.
Please don't ask me for measurement results for Transparency, Details, Color/Texture and/or Dynamic/Soundstage criteria!
Hmm if you are not budget conscious or do not want to waste your time on trying different opamps, then I think you may get it. If you are short on budget, then just get the best DAC / sources that will sound good on your system.
Sensible advice. I'm pretty happy with the OPA1656 but would like to try some more... to be truthful the journey of experimentation is part of the fun. I definitely fall in the budget conscious category tho so maybe the Bugatti of op amps isn't for me.

I assume this should sound better than TPA3255 with high sensitivity speakers?
What power supply do you recommend for this?
Genuine LRS-350-36 is good. The TPA3251 module (Sylph-D100) has better clarity and transparency than the TPA3255. But the highs are cleaner on the TPA3255.
For overall balance, the dual mono (Sylph-D400) sounds the best to me.

Hello jlesterp and Happy New Years with all the best wishes that come with it
Can the MEAN WELL ERPF-400-48 switching power supply not be a better choice with regard to its technical sheet, specificities and especially without fan ?
It is resistant to moisture and dust, which also looks interesting...
Its ripple (240mVp-p) and leakage current (<1ma/240VAC) are weaker and should therefore give better 'results' although the rated current is lower by 1.1A (8.3A instead of 9.4A) but it should be sufficient if we refer to the technical data of TI for the TPA3255.
She mainly has a build-in active PFC fonction
However, the 'availability' is only 70% from 50°C ambient temperature for the ERPF version while the LRS is always 100%.
This problem should be able to be resolved for the most part by removing the top cover of the power supply...
An important point is the operating frequency (450, 500 or 600kHz) of the TPA 3255.
Indeed, the rise in circuit temperature is directly conditioned by this parameter which gives better results when it is the highest.
Everything remains a question of compromise when choosing the box that will house the PCBs.
The more voluminous and airy the box, the less delicate will be the choice of the power supply and consequently of the value of the adjustment resistor for the choice of the frequency of use of the TPA3255
Can you give us your opinion and expertise ?

Have you tried this power supply? I think it can be a good alternative to LRS-350-48. Datasheet didn't mention low power mode in no load conditions, some supplies produce audible frequencies in low power (burst) mode.
Our TPA3255/51 amps use 600kHz operating frequency so it runs slightly hotter compared to when configured with lower operating. freqs.

Hi Wolf,
This would require creating an adapter with 2 of these OPAMPs per channel to replace the double OPAMPs provided for the SYLPH D200 MKII.
Either plan to buy 4 of these OPAMPs at 85 euros each, excluding postage !
AUDIOPHONICS -> This product is discontinued...

People hi !
I received my PCB 'Sylph D200 MKII'
The work done is simply exceptional and I would like to congratulate jlesterp: there is nothing at all to complain about regarding the quality.
It's an 'extra PCB'
I haven't received all the hardware to build my amp yet but I'll post new pictures as soon as it's finished, I promise
In the meantime, here are some pictures ->

I think jlesterp will comment

Thanks to Lester's great work, D200 Mark II amp was received, installed and running...already sounding more airy and more depth, and higher density than the other two 3255 amps I also own. The super low noise 48v regulated linear PS also helped (Ripple noise is 1/100 of a typical SMPS)

Nice, you can enable PFFB and use balanced source to get the best sound quality.

Hi everybody, hi Lester
I carried out several tests with different OPAMPs including OPA 1656 and I can say one thing:
really try your D200 MKII PCB with OPA 828 OPAMPs, the quality of the restitution is remarkable !
I 'looped' Tracy Chapman's 'greatest hits' album, which I know perfectly well, and the result is final concerning the voices, percussion and especially the rendering of the guitars, which is disconcertingly natural
Take the test for yourself and you will see that the OPAMP OPA 1656 does not have this quality at all in the rendering of the mids and even less in the highs which will seem insistent and incisive...
Personally my choice is made:
I keep my OPA 828 OPAMPs, what wonders
