Cartridge for ATP-12T


I have a Technics SP-25 with an ATP-12T tonearm.  I am currently using a Denon DL-103, and it is a really nice combination.  I would like to try another cartridge that would be a step-up from the Denon -- something that digs a little deeper and extracts more detail.  My budget is around $500. The ATP-12T is a heavy arm.  I am having a hard time finding lower compliance cartridge options that would work.  Any thoughts?

Thanks

Try the Hana LE for $500 (new). Favorably reviewed by HR recently in Stereophile!
@roberjerman Thanks for the Hana recommendation..both the EL and SL look interesting

@donvito..  Thanks for reference information.


I built that turntable. Suggest an Ortofon #1S. With a bit If shopping you can find one in budget.
I forgot to mention another rarity: Victor MC-1 which is relatively cheap LOMC cartridge with unique construction.

Playing with Direct-coupled Victor MC-1 cartridge on Sony PUA-7 tonearm. The weight of the armature in the MC-1 was reduced by using a super-lightweight micro-coil. The micro-coil consists of a wafer and a precision coil of approximately 1mm square formed thereon.
It’s accuracy and reliability are extremely high, while unit per unit variations are minimised. The weight is almost a one hundredth that of conventional coils. Employment of a coreless coil eliminates the possibility of magnetostrition. The magnetic circuit is constructed of a samarium cobalt magnet and an iron cobalt yoke in the vertical configuration for obtaining an excellent magnetic efficiency so that the merit of the direct-coupled construction can be fully utilised. Shibata (0.1mm square diamond) on Beryllium cantilever, output 0.2mV, frequency response from 10Hz to 50000Hz. Hard to find in working condition nowadays, an old printed coil is fragile. I got 3 samples and only 1 of them is working!

I was thinking to send 2 defective samples to SoundSmith, he said he could try to fix them, normally one channel is missing, but the diamond is like new. However, i was so happy with my perfectly working sample that i forgot about two others, one of them i got from Nandric for free :) He said it sounds more like a nice MM (which is a compliment for me).
I had this table and arm for about a year. The cartridge that I enjoyed the most was an older Nagaoka. Mated well and tracked well. You could get an MP300 for around $500. I would think this to be a superb combination.
Cartridge weighs 8g, yet should be able to track around 1.5 without issue. 
Just took a look and came back to edit post.  I used a Nagatron 360CE.
