I need some cartridges recommendation (low in price but high in quality, is there such thing?) for my SME 3009 II improved arm, it's light and made for high compliance cartridges. I tried Grado, and Ortofon X5, they both didn't sound good on it.
Thanks
Well, the Grado should do fine in a light arm....it's probably the tweeky nature of the Grado that let you down

The Ortofon X5 is a curious beasty...it
tends to like heavier arms (as do most/all moving coils), but it has a very weak bottom end as a stock cartridge and as a high output device, wants to be loaded at ~1-2K and that's not often available so it exacerbates it's sonic issues.
There seems to be 2 versions of the venerable X5....and older one with a 0.4gram effective mass that folks rave about. Later, it ballooned to a 0.7gram effective mass that predictably make it sound slow, bloated and weak bass in comparison to the lithe original. I have the latter/fatter one...and you may also.
If you're sticking with that arm - stick with cartridges requiring a light arm. The Audio-Technica's, Goldring's are those among current makes with a wide variety of prices (you didn't mention a price range)
I love the old ADC XLM series myself for light tonearms - but they are getting tougher to find as they are out of production now for 30 years
