Interested and would like to see more on your SP9. How do we proceed?
Advice on what preamp to select.
Hello
I picked up two Adcom GFA565 Power Amps recently and would like to get a newer preamp to go with these. Currently have a Crown IC150. Have found a Audio Research SP-9 MKII for about $1100 but am considering also the following: Macintosh C series in the range of the 34V or newer, or purchasing a Mac MX series preamp.
The MX 130 looks to have decent reviews just being used as a solid preamp for stereo use and has a phono section which I need. I know this is a question with no best answer but anyone have experience that they are willing to share?
Thanks
Kent

copied this from review on the amp The Adcom's input impedance at 1kHz was 47k ohms, and its output impedance was uniformly low—ranging from 0.02 ohms from the bass to the upper midrange and increasing slightly to 0.03 ohms at 20kHz. The gain of the GFA-565 was 27.1dB into the unbalanced inputs. I found that the three gain settings on the balanced inputs—0dB, +4dB, and +6dB—actually gave quite different readings. The +4dB setting was actually 8dB down from the 0dB, the +6dB setting was down 14dB from the 0dB. Unweighted noise was 70dB below 1W into 8 ohms Read more at http://www.stereophile.com/content/adcom-gfa-565-monoblock-power-amplifier-measurements#o0IIiIqQ6YtF... |
