Hifi Rose RS520

This streaming amplifier claims to be 250 wpc at 8 ohms and the same 250 at 4 ohms. Is that possible - and if so what does it potentially tell us about performance etc?

Thx

Hmmm - using a discrete opamp after the DAC chip for better performance usually has a rather detrimental effect. I'd rather stay clear if such unfounded claims.

250W @ 8 and 4 Ohm is possible with either a very soft power supply or a current limiter in the output stage or power supply.

Thanks. I wasn’t expecting it to double down to 500 but you always see a significant increase in power so wondering why the engineers implemented this design. Always a compromise but what’s the benefit?

To protect the amplifier against overheating? Just speculating ...

It’s a class D circuit so not sure that’s it
