OP, the 300K is the input impedance. The input sensitivity of the amp is 2V for rated output, and the V gain is 24db, a little less than the norm of 26-28 db. Just a friendly fyi. My best, and ENJOY ! MrD.
Passive preamps - differences between technologies
Hello!
I have been wondering what are the main differences in the way some passive preamps are designed.
Some have resistors, some are transformer based.. What are the pros/cons?
More specifically, I'm looking at Music First Classic/Baby Reference V2 vs Hattor the Big or a Tortuga.
I'm looking for an upgrade from Audio Research LS16, considering looking for ARC Ref3 or a nice passive. My amp is ARC Ref150 (which is a lovely thing and I feel like the LS16 is holding it back) and phono pre is RCM sensor2 mk2 - so there's enough gain from the phono, the power amp has 300k ohms input, my DAC can output 1-3V rms, I use interconnects up to 1m so a passive could be an option.
Thank you.

@mrdecibel Thanks! I was under the impression that the input inpedance is the main factor to determine how friendly a power amp can be to a passive preamplifier. And also the output of a phono stage or a DAC.. |
Lord to visit Prague again…. pack my REF5se in a flight case and be right there… Astute read that you don’t want to give up the dynamics… In my experiments… a buffer almost always needed …. hopefully you can find a way to trial a few of tgese devices while retaining the excellent store of value your ARC preamp represents…. Best to you…. |

If a Hint of Richness is on the 'to be experienced' list. A Cable with D.U.C.C Wire has the capability to produce this Tonality e, as a very subtle influence, the thickening up of the mid's and lower frequencies, is a typical effect from the Cable, that has been perceived across a few systems I have loaned the Cables with this Wire Type to be used in. Because the Wires Tonality is perceivable when a Group has been at a Demo' of it in use there has been a mixed response/thoughts disclosed on how it is able to create an impression. |
