MP150 or MP200

As I have said previously the mp150 is an excellent cartridge but at present prices not sure it is THAT much better than the mp110, both of which I own and know very well.
The mp200 would likely be the next step up from the mp110 imho if not for the fairly recent price hikes .
As has been established there is a lot of competition at the $500 mark whether you go vintage or new mm/mi or even mc.

Best of luck OP, it is a tough choice at that price range but if you really like the house Nag sound then maybe the mp200 would be the right call.
YMMV

Do not take things so personally.
Did you not see the line in my post where I said you likely had some stellar carts I had not tried?
And I am really happy they work out for you so well.
Please share the same sentiments for those among us where they do not work out as well.
Thanks and stay safe

I have been reading Chaks posts for YEARS on vintage MM carts and tried quite a few out myself mostly based on his glowing testimony.
Unfortunately I cannot say that any truly lit my fire, most did indeed work just fine although I did have one ADC cart collapse the suspension within a week of purchase ( sent back via eBay for full refund so no big deal).

Not a single one of them could get close to any of my good MC carts, not one. Think Koetsu Black Goldline, Scheu Analog SL, Ortofon Cadenza Black. Even the Ortofon 2M Black was a lot better to my ears.

Now maybe Chak does own some stellar examples I have not tried and I wish him all the best and hope he sincerely enjoys them but for myself there will be no more vintage MM experiments, just sold the last of them this morning!

Late to the party but I have both the mp110 and the mp150.
The 150 is an audible improvement over the 110.
However I bought mine way before the big price hikes so not sure as I now would say it is the way to go.
I have heard the 200 is quite a bit better than the 150 and obviously the 500 is the grail but at what price now!
Pre price rise I would have said it was a no brainer but at $500 for the mp200 there is a LOT of competition.

Maybe look at comparable priced AT carts or Hana.
