Kumza Stabi S or Rega P10 ??

What about the Hana makes you know it wont require shims?  What do you mean by shims? For VTA or for azimuth? Using a tonearm that allows you to actually adjust these parameters is an advantage over the Rega arms. If you are set on using a Hana cart (totally valid) then I would not buy a P10.  I would find and alternative with an adjustable arm and have it aligned professionally.  Then your are set and can forget!  I agree with Tablejockey that getting the P10 with the best Rega  cartridge you can afford is a fine idea.  Don't worry about it sounding thin. It sounds great.

Got the P10 with the Hana red, listened for a couple hours last night. I am borrowing a set of speakers (New Sim Audio monitors) while I await my Falcon Gold Badges. so everything I am thinking at this point may not be the turntable. 

First impressions, are it sounds light, delicate, airy, decent bass. Overall I feel like I lost some warmth and weight I had with my previous TT. Tons of detail retreival, some of the best I've heard and I have owned MSB DACs and Antipodes servers before I went all analog. So far, I am just sort of luke-warm on the sound, don't love it, don't hate. This may all due to break-in of the cart, speakers are broken in. 

I may have to at least create the option for myself to audition the Feickert and see if I hear any significant differences. 

The P10 is not a warm or weighty sounding turntable. It sounds a little bright, and quite analytical. I found I preferred the P8, which had a fuller, warmer, and more natural sound, although gave up a litte bit of detail and drama compared with the P10. The Hana is a warm sounding cartridge, so what you are hearing is completely attributable to the turntable.

I think was working through the break in with the cartridge, I underestimated that apparently. Things are sound superb. Table and Cart are a lovely combination so far. Warm, tight bass, smooth, and super detailed but delicately detailed. 

I've had the P8 and P10 together in my system with the same cartridge for a lengthy period and the P10 is better all around. Not significant, but just better in every aspect. 

I can't disagree more with rossb but we all hear thing differently. I can only go by my experience and the handful of friends who also heard the comparison and all agreed the P10 is overall better. Not bright, not analytical, but retrieves all the music as it was recorded. Yes, it will present bad pressings as such, it's not hiding anything with a warm blanket. 

Give your cartridge time to break in, as well as the table. It's not really fair to give an immediate evaluation, especially on a new cartridge. I'm glad you are starting to experience the difference!
