Shure VP64, Audio Technica AT-804, Shure SM63


These mics are very sensitive.


The AT-804 is 600Ω. It sounds big with a bit or harshness at midrange. But it is a natural sounding mic.


The Shure VP64 is very elegant and impressive. Very loud and sensitive. More bandwidth than AT-804 which may or not be a advantage depending on application.


Signal path:


Male speaking or singing voice - mic at close distance - Sony TC-D5 Pro - Sennheiser HD580


The VP64 may sound a bit harsh too at mid midhigh range. But it is a very natural sounding mic. With a Pleiades 330mH high pass filter some bass heaviness is removed when used for singing. With a Pleiades (130Ω,40mH) gentle slope high pass filter a very bright and treble extended sound can result. This filter is not very suitable for the AT-804 which is 600Ω, different values of R,L must be used.


The SM63 sounds much more bright and less bass heavy possibly making it very suitable for studio singing on a backing track. It has much less handling noise that the other 2 mics.


Wouod the little harshness at mid midhigh range of the AT-804 or VP64 disappear when used with an electron tube booster amp such as the battery powered Pleiades V6?
