A pragmatic view of cartridge expenses / many questions

If the assertion (premise) is not true than deduced statements
from the assertion can't be true also. In +40 years in this hobby
and more than 60 cartridges I never wear out any of them.
Is there such thing as ''imagined wear''? 

Hi audioquest4life
Pirelli P Zero have always been homologated for the fastest Porsches.
Dunlop have recently joined.
That said, like you I favour the Michelin Pilot Sport Cup.
At a recent Club trackday I counted more than 4 to 1 on Michelins and not a single Dunlop.

Top carts - vdH yes.  Ortofon yes

Clearthinker, Michelin is now making N0 tires again so you can feel comfortable putting them on. The dealers will never use anything but N0 or N1 tires. I have seen new Porsches come through with mostly P zeros as you suggest but also Michelins and Goodyears! P zeros don't last a whole lot longer than the track tires. I burn then up then switch to Michelin Super Sports now Sport 4S.

Audioquest for life. I have not yet owned a VDH cartridge. They are very compliant for MC cartridges and my current arms are probably a bit too heavy but your SME V's are perfect. My next arm will have adjustable effective mass (Schroder or Reed.) VDH reviews are uniformly good. Next time around (after I get the arm) I'll do either a VDH or Allaerts.
Right at the moment my Favorite MC is the Lyra atlas (not Lamda) followed by the Ortofon Windfeld Ti. But as I have said in previous posts the Clearaudio Charisma is the nuts for high energy music. It's presentation is a little on the darker side, unusual for a Clearaudio but it is by a fair margin the most dynamic cartridge I have ever used. Percussion is otherworldly and the bass is not far behind. While not as detailed as a MC anybody listening would think it was one until I spilled the news. It is certainly superior to any $2000 MC cartridge that I have heard. MM buyers will not spend as much money on a cartridges as MC buyers will in general. I think this forces the prices down. To bad MC buyers were not more frugal. 

Nandric, I think you are right. But, it is a good reason to throw at the wife to get a new one:)

@audioquest4life,

Responding to your OP, I do approach with life cycle cost in-mind.  I have two tonearms a VPI 10.5i with Soundsmith Carmen and a VPI 12-3D with Soundsmith Paua.  I setup the Soundsmith Carmen based on life cycle cost (got a great a price on the 10.5i).  I listen to music ~3hrs every day (~1000 hrs/yr).  I have a number of records that are not 'audiophile' grade and why waste the Paua.  I am partial to Soundsmith because of their acoustic presentation; they are very easy to drive - you not need a $$$phono preamp to get good results, they are quiet, and the cartridges can be 'rebuilt' - not retipped, but rebuilt with a completely renewed suspension.  So, when you get the cartridge back - its essentially new and requires a break-in period for the new suspension.   I purchased the Soundsmith Carmen MKII (hype-elliptical diamond - VTF 1.45 gm) on sale for $699.

From a life cycle/performance cost, the Soundsmith Carmen MKII is a bargain. Because of the low VTF, you should be able to get 1000-hrs and Soundsmith "rebuilds" the cartridge for $199. So a 2,000-hr cost is [($699 + $199)/2000-hrs] = ~$0.45/hr-use, and at 3000-hrs = $1100 = $0.37/hr-use.  

Compare that to an Ortofon 2M Black with Shibata stylus that is $750 plus ~$550 for new stylus, so the 2000-hr cost is $1300 = $0.65/hr-use, and at 3000 hrs cost is $1850 = $0.62/hr-use.  

Now for my Paua, I bought the cartridge on sale for $2500 and I am into the first rebuild ($550), so the 2000-hr cost = [($2500 + $550)/2000] = $1.53/hr.  However, one item to note is that Peter personally rebuilds all the top tier cartridges and turnaround can be 8-weeks. The Carmen is rebuilt by staff, and turnaround should be just a few weeks.

Of course, the above analysis is useless if you do not like the sound of the Soundsmith Carmen/Paua, but the analysis is presented as a way to access a cartridge life cycle cost. But, make no mistake, digital can beat analogue life cycle cost easily because the average laser or digital component MTBF is at least 5000-hrs (but sadly the 30,000-hr MTBF of the Phillips benchmark glass optic lasers are history). However, if you have the financial resources, life cycle cost means nothing, but this OP was asking if a pragmatic approach was used.
