Ortofon Anna or Transfuration Proteus?

I am now using SPU Gold cartridge with Ortofron 309 tonearm and Garrard 301 turntable, together with a Bob's Device SUT to Shindo Monbrison preamp.

I am considering upgrading the cartridge to either Ortofon Anna or Transfuration Proteus, looking for higher resolution and separation, more dynamic and air, and better tonal colour. (...am I asking to much?)

Much appreciated for your input.

i don't think there is anything better than Atlas....I would be very pleased with Aetna also.
Thank you for your suggestions on Lyra Atlas. I would really like to have it but it's too expensive for me. :-(
I have heard both the Ortofon Anna and Transfiguration Proteus. Both are excellent cartridges. Here is my take on them and the Lyra Atlas (which I have also heard extensively - my friend owns the cart):

Ortofon Anna - very smooth cartridge - solid bass, very detailed yet smooth highs, and by my ear, somewhat sterile midrange. Dynamics also lacking a bit for carts in this price range.

Transfiguration Proteus - different than the old transfigs which were on the 'romantic' side of voicing, this new transfig is super fast, great PRAT, solid bass, and very good highs although not quite as good as the Anna. Midrange can also be a bit thin.

Lyra Atlas - great detail, great bass, dynamic as a cart can be, but also more sterile sounding than the other two above by my ears. transparency great, speakers disappear, but not a very 'musical' cart, but very accurate. Somewhat unforgiving.

If I had to pick between the Anna and the Proteus, I would probably pick the Anna, but remember the Anna is $1,000 less expensive than the Atlas, but $2,000 more expensive than the Proteus.

A cart you haven't mentioned in this price range is a Dynavector XV-1s. It retails for less than the Proteus, yet by my listening tastes and ears, outperforms both the Anna, Proteus and in several ways, the Atlas too.

The XV-1s is very musical and is 'solid' in all areas - imaging, detail, bass, smooth highs and a liquid midrange. If the above carts have some categories where they rate 10/10 in some and 5-6/10 in others, the XV-1s rates 9/10 in just about everything. It is definitely a cart you should consider in your cartridge quest.
I am somewhat wary of generalisations which rank audio components given the infinite variables involved and this is particularly true for a phono cartridge . For example , how many analog aficionados can truly claim that their tone arm wire is optimally burnt in given the small mV that a cart generates. Add to this , cart alignment, loading, TT speed stability, isolation, VTF and how it's measured, VTA and the list is pretty long if you get my drift. I can be pretty confident about some of these issues in the context of my own system but I am not sure about any other system. YMMV.
Sure anyone serious about this hobby can judge good sound but can you with some modesty pinpoint the causes for poor performance and identify the components responsible. IMHO , if someone characterizes a cart as sterile while the majority of ownership experience points the other way, I would not be swayed by the minority experience.
Just my 2 bits.
