It depends. R2R11 may sound fantastic. On the other system ground loops can ruin the internal calibration process and then the higher priced R28 with better protection (especially a new version with dual transformers) will show a difference of a magnitute. If ground loops or power noise do not affect your system, a difference can be minimal. A new version of R2R11 receives the same upgraded DA-8 modules.Thanks I want to make sure its a significant upgrade if I'm going to spend 1200+ I bought rme before and didn't enjoy it as much.
This is what you always get better with R28:
1. A balanced DAC (two DA-8 modules per channel) cancel some type of distortions.
2. Better headphone amplifier. There are members who claim it control bas of HD600 much better. I am not sure about it, as I own HD600 paired with R2R11 and I can't imagine it can be any better.
3. Better jitter rejection in the CPLD FIFO circuit. R2R11 depends entirely on the Amanero module.
4. A choice of oversampling and filters, including (3)? filters for NOS mode. Those who listen a lot to the modern music mastered for delta-sigma converters prefer 8x oversampling mode. I would always chose NOS sans digital filter for classical, jazz and acoustic pop/rock. It gives the most natural harmonics, the closest to the life performance. You have it on R2R11.
5. More interface ports.
R2R11 is an enormous value product. I can call it a bite. A something that opens your mind to the high-end Audio GD products.
R28 is overpriced in my opinion. It has still a good value comparing to the competitors, but I take it on the ladder of A-GD products.
R27 is your end game and it doesn't cost 3-times more than R28, unlike competitors.
In other words, the best value is R2R11, then R27.
