Should I buy a VPI SCOUTMASTER. I OWN 25 RECORDS.

If you have 25 albums if it were me I wouldn't spend thousands on hardware not even knowing if I wanted to pursue it.  Just common sense I think.
Just get a decent phono stage if you don't  have one, an entry level turntable made by a reputable manufacturer,  spin clean washing system (I know its a manual set up but it really works).
For phono stages I like the musical fidelity entry level preamps they have plenty of gain and you don't have to fiddle with them a lot.
If you decide you like it then reinvest later once you know what you are getting into.

It’s a chicken or egg scenario.  Do you build up a record collection and the buy a good table, or buy a good table and then build up your record collection?  

Oops, my mistake.
But then it’s just like my argument how inconvenient the MC cartridges really are. Does that mean a Hana charge 80% of retail to rebuild or completely change their cart officially via distributors ?

Yes, MC cartridge replacement is typically about 80% cost of new. I don’t consider it very inconvenient. It’s simply a a matter of mailing the old cart to the dealer and receiving a brand-new one in return. That’s how most MC cart exchanges are handled these days. It’s not like Soundsmith, where you have to wait for them to retip your original cartridge, though that’s probably still the case with some esoteric carts like some of the Koetsus.

So the only real advantages of MM are that you can order a replacement stylus and not have to be without a cart for a few days. That and you don’t necessarily have to realign it each time (though often times realignment is necessary as no two stylus/cantilever assemblies are truly identical).

One disadvantage of MM is that stylus assemblies tend to have a rather loose mating with their cartridge housings. Any slight bit of tolerance there will result in some amount of signal distortion vs the fixed assemblies of an MC. Further, MCs have the well-known advantage of a lower moving mass - similar to the advantage of Soundsmiths MI carts. Lower moving mass is a big advantage according to PL of SS, and it applies to MCs as well as MIs.

The problem with MCs in terms of cost is that most examples under $500 U.S. are inferior sounding to a good MM. People try a $350 MC from Denon or Ortofon, realize it’s crap, then swear off MCs all together. Typically, MCs under $1K don’t sound all that good. That’s where Excel stepped in and changed the game with their relatively affordable Hana series. I’ve had some quite respectable MMs with Microline and SAS diamonds. They’re good and I could live with them if I had to, but a Hana SL or ML are indeed in another league if setup correctly and mated with a decent phono stage. That said, one of the salesmen at my local hifi shop traded his Clearaudio Maestro V2 (Micro HD stylus/ boron cantilever) for the $450 Hana EL and didn’t look back. I was surprised by this but the guy is pretty well versed with all things analog.

@helomech Most of the well designed MM/MI have a stylus assembly that screwed to the cartridge body (ADC TRX, Sony XL-50, Technics P100 and P205 series ... ), but even without that screw pulling a stylus away from a Grado cartridge is a challenge, did you ever tried ?

Some of the best MM cartridge have extremely low moving mass too, read about Audio-Technica AT-ML180 OCC or Technics P100c mk4 just to name a few with the lowest possible moving mass.

I do. It’s not that simple if your LOMC cartridge cost $4500 and to replace it (when the stylus is worn) you will have to pay 60% of the new cart again. It not always 80%, but even 60% from $4500 is $2700 ! In the MC world even $4500 is not the highest price and i had those cartridges before (never again).

The Excel stepped into the game in the 70’s with wide range of cartridges, they made cartridges for others like SAEC and Argent long time ago. WHy do you think their new design is any better ? Here is my thread about earlier Excel Sound work for American brand Argent in the 80’s

Totally forgot about the stylus!!! Ok, so if I get a Hana SL how long will it last vs say a 500 dollar moving magnet?
