I’d recommend against it. I have an LS-28 and a Rogue Stereo 100 which has 200k input impedance and this combination works well. However I once tried to run a subwoofer with a 10k line level input impedance in parallel (causing the LS-28 to effectively see about 9.5k) and the neither the LS-28 nor the Rogue liked it a bit. Sound was distorted and the power tubes glowed red. The ARC recommendation of a minimum 20k load appears to be there for a reason.
Question About Audio Research Preamp Specs
Hi,
I am trying to understand Audio Research terminology while looking at their product specs.
For example, for the LS28 OUTPUT IMPEDANCE, it reads "600 ohms Balanced, 300 ohms SE Main (2), 20K ohms minimum load and 2000pF maximum capacitance..."
What does the "20K ohms minimum load" tell me?
I am running a McCormack DNA-500 and it has an input impedance of 10K Ohms. It would seem that the amp would be compatible with this preamp based on the 10X/15X minimum rule of thumb.
My concern is that the AR spec is telling me use amps with input impedance of 20K ohms and the DNA would not work well.
Thanks for listening,
Dsper
