Springbok, good thoughts from Nsgarch above. Also keep in mind that, as a mechanical transducer and even after breaking in, all cartridges need to warm up a bit during each listening session, just like dynamic driver speakers. Before a serious listening session, I always play mine for about an hour with some complex and demainding music (e.g., organ) before sitting down to listen critically. You may also find that after that first 50-150 hour bread-in period (varies by cartridge), the suspension loosens up a bit and you need to readjust the VTA to compensate for the cartridge now riding a hair lower.
Good setup is critical to getting the best sound, and don't expect to shift between 150gr, 180gr and 200gr LPs without getting a change in sound due to the change in VTA that results from the varying thickness. Many of us end up adjusting VTA for each weight vinyl, and must keep in mind that all vinyl was not cut to the standard cutting angle so their can be LP-LP variances. This will depend on how sentivie your 901 is to cutting angle variances, some cartridges are not as sensitve to this as others and I don't know about the 901. Let your ears be your guide on this.
Unlike Nsgarch, I would plan to set up the cartridge optimally when new, but then plan to readjust as it breaks in. Cold out of the box, some cartridges can sound awfully good. I wouldn't angst over it, though, because as Nsgarch says, it needs to break in.
I also highly recommend you read and follow Lloyd Walker's advice for fine-tuning your turntable setup:
