Agree with all the others that you need to give this some time, and within your window of auditioning that means playing music through it 24/7 while in your possession. What I am less clear on is why you imagined this preamp would be a significant step up from what you have? If your goal is to match the Counterpoint linestage but get lower noise floor in the phono stage, I think there have to be better options than spending all that money on a new C2300. Why not keep the line stage you like and invest in an alternative phono stage? Further, the MAC has lots of functionality which you may or may need but is part of its price. I considered one but at the end of the day did not want to pay for lots of inputs and features that I did not require in my system -- everything that's extra costs, and with dealer mark up, it means compromises of some kind in the areas that matter most in your system.
