Analog Upgrade Suggestions Welcome


I am thinking of making several upgrades to my current analog rig.

First, I am thinking of upgrading my VPI HW19 MKIII to the MKIV. I would like those with first hand experience to tell me if the upgrade is worth the money, and what I can expect to hear in improvement. I am currently using the SDS and SAMA modifications.

Second, I am thinking of upgrading my cartridge. My Sumiko Talisman Alchemist IIb is almost 15 years old and is ready for retirement. Some A'goNers have recommended the Shelter 501. I didn't want to spend more than $1000 for a cartidge as the majority of my listening is still redbook CD. I am open to other suggestions. I want the best cartridge for the money. Also, I am leary of buying such a fragile item used. I have heard others on A'goN say they'd never buy a used cartridge. Please share any experiences out there; good or bad.

My current cartridge has an output of 2.0mV which I assume means high output. Will I need a step-up transformer for a low output cartridge? Is the Shelter 501 at 0.4 mV considered low output? My Classe Six preamp has a phono section. The preamp comes with resistors that the user can change out to match the volume control knob position to the level of line components. I assume I'd need to change the resistor I'm using with my current cartridge. Otherwise I'd have to turn the knob way up to get enough gain with a cartridge with an output that's 1/5 that of my current cartridge. Is that correct?

Thank you all for your help and suggestions.

Cheers!

I was just offered a Grado Reference brand new for $900 from a dealer I've dealt with in the past. How does it compare to the Shelter 501?
I note that the Grado Reference is a moving magnet cartidge. My Alchemist IIb is of the moving coil type. Has the technology evolved over the last 15 years to the point where moving magnets now have the resolution and finnesse of a fine moving coil?

Would the Grado Reference mate well with my 1990 vintage SME 309?
