The fact that Lyra has a particularly (abnormally) sizzling
lacking body treble (most obvious in sounds of Cymbals) is very apparent. I
have not heard anything like that in other cartridges.
The Lyra carts are designed to move all their energy from tracking into their
body and from that one into the Headshell from the Arm. When a Arm is used
which is simply inferior (and there are more of them out there than most will
believe) in that energy transfer - or has weak bearings - you get a lot of high
frequency problems while listening. It is not the cartridge, it is the Arm (+
Turntable, depending how the Arm mount was designed).
Zyx carts for example are exactly the opposite. They run well in ANY Arm, they
move no, or nearly no energy into the Arm. They make life much easier.
Lyra carts can show huge differences in Performance (Titan i is very famous for
that) , they CAN show, how good your System really is. Maybe there is one or
the other exception, but the Delos is not among them.
Arms are a special chapter, everyone thinks, when such a unit is ready to buy, it
is perfect and will solve all problems. Did you never ask yourself why some of
the most weak designs - technically - use wood? :-)
