RA1570 Integ. DAC/Amp vs RC1570 preamp/RB1552 mkII combo

[capall]

Hi,
I'm considering the RA1570 Integrated DAC/Amp for a 2 channel setup, and possibly to combine it with a AVR for a 5.1 setup in the future. 2ch though is my main priority. My budget is under $2k and have a pair of B&W 683 speakers

However, does anyone have any feedback on how the RA1570 Integrated DAC/Amp would compare to the RC1570 preamp/RB1552 mkII combo. The RC1570/RB1552 look like they have the same specs as the RA1570. I realise the RC1570/RB1552 combo would need a DAC, but it would be great to know if there is much of a sound difference if for example using a DAC similar in quality to the RA1570 Integrated DAC/AMP (I'm guessing its DAC is in the $500-700 range).

I believe the prices are as follows
RA1570 $1600

RC1570 preamp $999
RB1552 mkII 2ch Amp $999

Thanks

Hello over here too...

Just so you know, the RC1570 has a built in DAC too.

yes, you're right Audio_elf. I missed that.
So then that makes them all the same or it appears, the only difference is that the RC1570 and the RB1552 mkII exist in separate boxes wrt to the RA1570

I have no experience with the rotel pre/pro combo. However, I do own the ra1570 along with the b&w 683s and I am very pleased with the sound.
