I need help. I am currently using a Parasound model 2100 preamp. I was told that the Benchmark DAC-1 can also act as a preamp. I noticed that there are no Tone Controls on the Benchmark though. So will I be getting a flat tone all the time if I use the Benchmark DAC-1 as a preamp? And if I do decide to use this as my preamp, how will I connect it to my Cambridge 740C and my Parasound 2250 amp? OR, can I still choose to use my model 2100 preamp? Meaning connecting the DAC-1 to my 740C only? And set the back of the DAC-1 to fixed instead of variable? On the back of the Benchmark DAC-1 are L and R pots for what? Are they to be used when the setting is variable? I think the DAC used by Benchmark for the DAC-1 is made by Analog Devices so are they better compared to the two WM740 built inside the 740c? My post sounds so much like audio nervosa, it probably is but I appreciate any feedback if anyone has had any experience using the DAC-1 from Benchmark.
