AND HE SCORES!,congrats on the new preamp!

the c-28 is a great sounding preamp & is hard to beat for 2 channel stereo,it will also sound very much like the new model solid state mcintosh preamps(with tone controls) costing much much more

mcintosh voices their preamps to sound similar if not the same.
the c-28 is not a pre/pro its just a pre (preamplifier) & its resale value is around $500 unless you have both factory boxes then it jumps up to around $650 if its a mint unit,the resale price is greatly affected by the condition of the unit,any scratches anywhere,nicks on the end caps,bubbles behind the glass face(usually around headphone input & panloc's) any missing washers behind control knobs,any defects or mars will detract from the resale value.
all in all its a great sounding preamp & was built to last 2 lifetimes as is all mcintosh gear.
