SylphAudio's High-Performance Amplifier Modules

[SylphAudio]

Already got the SMPS2000R for testing our SE800, hope we can try your SMPS next time

Sure, I will make sure that you will test something soon.

Thanks

Hi all,
Following this thread with interest.
What sort of cooling would I need for 7 or 9 of the SE800 modules in a single enclosure?
The application is my theatre. Currently running 2 Crown CTS 4200 and a Samson S720 in a 7.2 configuration.

Hi, passive cooling is enough for SE800 modules.

Great, thanks

Inductors for SylphAudio's class-d modules were not only selected for the THD+N score, but also for harmonic profiles.

Is this true of the latest FB-360 modules? If so please say more about the harmonic profile you target.

I think I selected it for THD+N for D400M P05 and FB360 when I tested on the variety of inductor samples, the ones installed are better than the coilcraft 10uH AGP/VER2923. (on par with coilcraft 6.8uH ones)

Target harmonic profile is that the H2 should be higher or the same as the H3 for FB100 and D100

Hello, I'm planning to "build" a quite large amplifier to power a 5.1 setup to be able to mix 5.1 movies/music at my own place

I am currently looking for class D modules and I am planning to go for 3 x 3E AUDIO 260-2-29A (80Hz-20kHz) and 1 x 3E AUDIO 480-1-29A (20Hz-80Hz)
3e audio modules are a bit cheaper, are sold at Audiophonics (I'm safe with a warranty) and have got a review from Amir

But I'm looking for modules with better Power VS Distortion, because the increase of distortion in higher frequencies scares me a little bit and might not match the quality of my speakers
The 3 modules needs to be able to produce 2x60W peak 8Ohm which is not the case with the FB100 sadly, might be only 40 clean watts? but I can get away with that

Is there anything that could make me want to go for 3 x FB100 (80Hz-20kHz) and 1 x FB360 (20Hz-80Hz) instead ?

I lack of reliability + performance data and user experience

I'm planning to use MORNSUN LOF550-20Bxx units for your information


On the other hand, I might wait for the new NCx122MP and NCx252MP + DSP2-114 from hypex but I'm not sure I can wait this long

Thanks, and have a good day ! Keep it up

@daniboun Hello, I have some questions if you could have some time for me. But I can't DM you, can you DM please ?

Hi, we've already sent the FB360 and FB100 to ASR for review a few months ago. Although they use SpeakOn connectors, which Amir mentioned he doesn't have an optimal setup for yet (he uses his SpeakOn wires on high-power PA amplifiers). FB360 and FB100 have a deeper PFFB configuration, so we expect them to perform better than the competition. FB100 has been upgraded with all OPA1612 opamps, while the FB360 still uses a mix of OPA1612 and OPA1602. We've resent the upgraded all-OPA1612 module 2 months later, so Amir has to swap out the newly upgraded FB100 module over the old one (comparing old vs. new module would be interesting though).

As for the choice of power supply for TPA325x, my opinion is that the PSU affects the smoothness of the highs. Low registers, not that much unless the PSU is horribly substandard.

The power supply definitely affects high-frequency performance. I used two different batches of Topping's stock PSUs for the PA5, and the difference is clear.


One batch sounds brighter with more high frequencies, widening the soundstage. However, the sound quality fluctuates randomly between bright and dull. Sometimes the bass almost completely disappears, leaving the mid-highs heavily emphasized. The other PSU sounds much softer and remains stable. Not sure what the technical principle behind this is.
