...first RIAA is needed for the records produced before 1954 i.e. before RIAA standard of mastering records. So RIAA equalisation makes nothing to the records produced after 1954(or maybe earlier).
Second somehow the placement of the musicians in the stage had been altered as to comparing to the no-preamp. Every instrument sounded brighter but at the same time clearer. The worst thing happend to the human voice that is being first echoed wherever you need it and wherever you don't and again changing(doesn't matter sometimes to worse sometimes to better) depending on the recording.
The thing is that my analogue rig is well established and reproduces darn good whatever had been placed on the record and in most of its cases do not need a correction or any artificial imaging. It has no floor or ceiling and images to the level of live performance exept huge symphony orchestras that need to be heard live only.
How can Tact reproduce 8Hz? To tell you simply it can't since digital freequencies are limited. With larger number of upsampling you may improve bass but the highs will cut off. So any digital device might be good for all audiable freequencies but in order to image it has to use a digital correction engine like in Tact.
