Marketing buzzwords , many dacs and processors use oversampling upsampling and all kind of mathematics to process audio, mostly to counteract filter artifacts and such problems move the noise spectra somewhere benign etc. My meridian HT preamp uses 64bit floating point internally, but it still a "24 bit" machine. You must simply have processing space that is transparent to the incoming signal.
Btw there is no true 24bit dacs either how can it be an 32 bit, analog noise swamps the performance around 20bits for most practical systems, you need cryogenics to get to -144dB for 24bits. I read somewhere that the thermal noise in an 100 Ohm resistor is louder than that, the atoms is vibrating creating noise. Btw nowdays with moores law and all, I'll expect even the most humble ht reciever to use dsp's with 64bit fpu. Maybe it was expensive 5-10 years ago. But the kit looks very god anyway if you read the specs. It seems to achieve *very* good data, so it looks like a *really* good DAC . Just don't mind the marketing to much. There must have been some serious engineering effort going on here. Not just some Audiophool sticking tubes into an existing design, I would not mind give this one a listen.
