Regarding the gar2520 it says on the CAPI website it says "Sonically, it's hair-splittingly close to a vintage Huntington 2520". I wanted to hear the difference so I compared the gar2520 to an original vintage Huntingdon 2520 (I have one for sale - check my other listings) and I agree, you would be hard pressed to tell them apart.. I have quite a few of these so just letting two of them go to free up a bit of space.
They sound amazing, any signal going through them sounds better. The item "CAPI API VP28 Preamp for Lunchbox" is in sale since Monday, February 05, 2018.
