Opinions on Hypex Plate (FusionAMP) Amplifiers?

Its only a 3m cable but it does have a relatively tight bend at its input into the FA253 (and it's not a higher quality cable) - so its seems this cable is the problem.

There might be right angle adapers for toslink cables. There are for sure toslink cables that are terminated with a 90 deg jack, tjis would relieve the cable at the FA side.

I wanted to share that after just 6 months of procrastinaring I can confirm that Fusion amps output usable spdif signal.

Wiim mini -> Hypex Fusion -> Yamha AVR it all worked together and output music. Digital volume control worked as well on both Fusion amp and AVR. This opens options for people on a budget that want to extend their Hypex chain, for example with a sub.

Working on a build right now using a FA253 and FA501 per cabinet in a build right now. Very impressed so far but they do lend more to a technical user who likes to press buttons and screw around with DSP. Playing with a DIY take on a build between Pitt and Giblen Super Wax Minis and a poor man’s B&O 90s. Basically just a large all in one studio monitor build.

The crossover design in Hypex Filter Design software is fairly easy to pick up on. The only issue I have is with the DAC A/D chain and not being able to hijack analog audio off the DAC and run it into another amp as an audio input. For example, in my setup, I currently have to feed analog input into the FA253 in order to make use of analog through to the FA501. Ideally I would like to feed digital in via optical to the FA253 and be able to still use the analog through to the FA501 which doesn’t have a digital in.

Don't worry about A/D chain as its really transparent. But You can go into FA253 digitally, and then use a DAC accepting SPDIF coax input, which will serve FA501.

So toslink -> FA253 -> coax spdif into external DAC -> FA501

So toslink -> FA253 -> coax spdif into external DAC -> FA501

For that price, you can buy a FA502 with digital input. This way there would plus one amp and DSP channel and don't have to "mess" with the A/D conversion.

FA253 and FA501 are already there as I understand. For an extra ~30 usd (like sms ps100) signal stays all digital on FA253 and still interface with the analog FA501.
