Redgum RGi120 or Simaudio Moon I-5?


I have the opportunity to upgrade my Sima W-3050 amp and P-2001 pre-amp to either a Redgum RGi120 or Sim Audio Moon I-5 integrated. My current speakers are Soliliquy 5.0s and source is the Cambridge Audio 840C. I can't audition either amp so I'm wonderimg what of the two amps would you recommend?

An easy choice at least for me, having owned both units, and depending on your priorities:

For resale value, the Sim, by a wide margin.

For sound, and dependability, the Redgum. By a wider margin.
Thanks. I went with Redgum.
