help me to understand the gain


I have a problem that the gain is too high. I can only turn the volume knob to 7 o'clock position, with the 0 at 6 o'clock. I am sort of ok when using my computer where I can lower the volume in iTunes. But from my CD player, I cannot.
I am using Maverick Audio DAC, PrimaLuna Progloue 3, McCormack DNA-1, and B&W CDM9NT.

CDM9NT - 90db sensitivity
PrimaLuna - gain 12db(4x), input impedance - 100k Ohm, output impedance - 2800 Ohm
McCormack - input impedance - 100k Ohm, 150Wpc RMS into 8 ohms (21.8dBW)

is that my equipments are out of synergy? I just bought a pair of Zu which is 101db sensitivity, does that mean it will be a even bigger problem? should I buy another preamp with less gain, or should I buy another amp with less power output?

The McCormack DNA-1 does have a pretty high gain but still a sweet sound. Even its little brother the DNA.5 Deluxe that is really musical has a gain of 29dB.

At one time I had a McCormack DNA-1 Deluxe, with a McCormack TLC-1 Deluxe preamp with signals being fed to it from a McCormack DAC-1 and an Oppo BDP 83 as a transport. Speakers were a rebuilt pair of KEF 104/2s that have a 92 dB efficiency. The room they were in was on the small side and the sound would get really loud with volume a little past the 9 o'clock position. The soundstage was great and the sound was crisp though.

I agree with some of the posts on top. You may have to modify or change your preamp to one that has lesser gain or your source to one that has a lesser gain or warmer sound. I say keep the DNA-1 but I have a heavy bias toward McCormack gear.
