***As a final note, if what I just wrote sounds less than ideal, please understand that the "magic" you have will come at the expense of some things. You will miss it once it is gone. But it isn't for all music. Enjoy!!!***
Because our systems are different therefore our results will be different in fine ways,in fine graduations, one way or the other. So the degrees of weakness and perceived strengths you perceived in the combo might be how the rest of your system interacts with that combo for the better or the worse and therefore influence the final assessment of a cartridges forte.
I think its possible to pull and push a cartridges perceived signature ,within limits, by the myriad of contextual changes you can make by switching cables, mats, shims and components.
I'm exploring those limits through experimentation with the use of different mat materials, shim materials between the cart and arm.
I am having a couple of shims of different thicknesses of titanium made up to see how it will influence the sound. I currently have a tiny panzerholz shim installed and like the results. With each kind of shim i have to try several different mats because how one material interacted with the other might not react in the same way with the other. One change effects the others.
When i think of the influence the lenco is having on the combo, its difficult for me to gauge that without having heard a low noise table of the acustic or vpi type to compare it to. If i did it would make the task easier.
Second hand reports have indicated that both have their virtues. One has more detail and a lower noise floor while other produces more noise but is musical in its own way. One has a masters in math the other in art. The comparison was between a acustic raven 3 and a dobbins garrard i believe.
Sometimes i think maybe the wood plinth is a wonderful compliment for a aluminum based armtube. Adding a little warmth in the midband to a arm designed to be very resolving. But again in the end i have no other reference. I have heard a vpi mark 4, a scout and a rockport though.
At best i can hope that the difference between my lenco in wood plinth and a table like the acustic is similar to the difference between the TW/allaerts combo and the schroder sq/titan combo comparison.
I like to believe my wood lenco with panzerholz armboard adds some earthiness, warmth, body and texture to the final overall tone of the allaerts.breuer combo that can only come from wood based materials.
Mixing, the resonant signatures of metal, wood and plastic based materials to produce a final tone is a fine art.
For example if i want the allaerts to be more agressive for rock i can produce that quality by putting slate under my amps and influencing the final tone. If i want my sound to be a little more softer and romantic i bet i could acheive that by putting my amps on american walnut.
So i dont feel 'stuck' or feel that the allaerts magic is less than ideal for rock because i haven't drawn that conclusion yet with it. I can identify with your descriptions but i dont know if they transfer exactly to my experience and situation for the above named reason which i am trying to articulate.
The allaerts like every other cartridge is 'colored'. With my fast amps, dynamic phonostage, the allaerts powerful neodymium magnets, my speakers neodymium magnets, the speed of the breuer, the speed of silver wiring, i don't feel that my rock lacks dynamics, speed or that the music prettied up.
ACDC "you shook me all night long" sounds powerful, fast, toneful, clear, aggressive and extremely dynamic and at a very high level. In this regard people should not consider it a romantic cartridge because it is not soft like old definitions and understandings of that concept. This cart is a departure from that. There is a way in which it is "beautiful" but it should not be called romantic. As i'm sure you would agree.
What i'd like to say is that i really do feel it has inherent in its design the potential to do rock very well, using my own fender strat and biting hiwatt tube amp as my barometer. So i know what "grind" sounds like.
Anyways...as i continue to tweak and experiment i will try to steer the sound with this cart at the front, to a sound that is more and more blind to musical genre. In general as a all round performer in my opinion, in my system its already pretty close.
