When playing back a live recording on an MZ-RH10, is there any way to get a display of the recording levels? I can't seem to make sense of the owner's manual in this matter... Thanks!

I recorded a blues show using Sound Pro SPSM-4 mics (single point stereo) into a battery module and into a Sony RH10 Hi-MD portable. Trouble is, I accidentally (and stupidly) plugged the battery module into itself and the mics directly into the RH10. The recording (made in PCM mode) came out basically fine--the frequency response was there and the meters showed the levels peaking near the top end. But when I played it back, it sounded like the levels had been set too low--hissy and lacking "punch." I'm assuming this is because the mics weren't plugged into the battery module (I don't know if the RH10's plug-in power supplies enough juice to the mics). Is there any way to get the levels sounding back up to where they should be? Thanks!

I'm really curious to know if anyone has noted any difference in sound quality in recordings made with PCM as compared with Hi-SP. Also, how does Hi-SP sound as compared with MDLP-2? Thanks!
