I agree with the comments about bass reproduction being part of what we think of as having good or bad prat / pace. Since bass lines ARE a major portion of the rhythm section, it's no wonder that it would affect our sense of "backbeat" or "tempo". As such, i think that many of these "pacey" systems are also noted as being "musical". Since "musical" is often used as a description of tonal balance vs "detailed" ( slightly bright ), it typically translates as the system being "warm" and smooth ( slightly elevated bass and soft highs ). As such, the logical deduction would be that it would easier to achieve "prat" or "pace" with a slightly warm system than it would be to achieve the same results with a "bright" or "forward" system. Since analog / LP typically sounds noticeably "warmer" and "fuller" than most digital sources, it is no wonder that many complain that digital seems "lifeless" / "has no soul or rhythm" / "lacks pace". Obviously, tonal balance affects our sense of "tempo". Make sense ??? Sean
