Advice on DAC/upsampler

I am seriously considering adding an outboard DAC/upsampler to my system to extract better sound from my large CD collection. Based on various reviews, the two units that seem to fit within my budget and offer good performance are:
1. the Musical Fidelity AC3-24 (which provides both 24-96 and 24-192 upsampling) (MSRP $1200);
2. the MSB Link DAC III with either the 24-96 upsampling module or the MSB 24-192k Network module ($700-800).

I have not included the Perpetual Technologies P-3A unit on my list ($800) because -- at this time -- it only offers 24-96 upsampling.

Do any of our readers have experience with either of these units. Since I have read most of the reviews available on these units, I know their relative strengths and weaknesses, so I am looking for direct, "hands-on", "heard it with my own ears" impressions.

Thanks,

Be careful about putting too much emphasis on upsampling. Much of the benefit depends on the implementation, and often upsampling makes very little difference as the added circuitry can easily cancel out the benefit of the upsampling if it's not implemented carefully. I know with the Link DAC, for example, many have found the upgraded power supply does much more for the sound than the upsampling, which doesn't do much at all by itself(despite what Sam Tellig would have you believe). In general it seems that DACs that use the popular upsampling chip du jour frequently don't garner nearly the benefits as the more esoteric systems such as the Audio Aero STARS system, dCs, etc.

I guess my point is that all upsampling is not created equally, and success depends on the method of upsampling and the implementation of upsampling into the DAC. Use your ears to make the final decision and you may find a well-implemented, non-upsampling DAC may sound better than many upsampling DACs out there, so keep your mind and ears open. Best of luck.
