I have an upright pleyel and a bechstein grand with a pair of 4038 and a R88 mk2 with Undertone MPDI.
Of course there are many ways to record a piano but I really enjoy the r88 . The coles always need some eq whereas the r88 do not. For an intimate jazz sound I put the AEA just above the hammers with an inclination. For a more classical sound I use DPAs. The coles sound nice also but the AEA is my favorite. I must try the trp preamps.
