preamp


I am looking to seek some guidance from  'experienced gurus' in this forum. I presently have a Tube mono blocks 'Auris Forte 150' it's from Serbia by Auris Audio paired with Tube( hybrid) preamp unicorn pre by unison research and speakers are Focal sopra N3. Sonically not fully satisfied. I am sure by replacing the preamp with a appropriate one I will achieve the 'highs ' and 'mids'.I want to replace the preamp and torn between 
- Mcintosh C2600
- Audio research LS28
- VTL 5.5 iii.
I even came across  chinese brand Cayin M11LS  tube preamp. In the used market I looked at the McIntosh C1100 for about 60% of the retail. Bit over my budget.
All theses are in the same price range $7500 USD.  I have never paid a full retail price on any of my equipment. Probably  Mac I could get the best discount . I am not able to try any on these at home with my system. Even if I listen to these preamps they are set up with differently  at the stores. 
Appreciate  fellow members  thoughts.

come to realize each component by them self are good , combining  them is the issue. I spoke to the Engineer at Auris he said ' great match with focal N3'. Just find the depression in the upper treble. I am not going to change my speaker or the amp  at this time, I am bent on trying different preamp. And try to test it with different speaker cable, presently I have the Transparent Audio. I like 80% try and get another 10% more than I am happy ( hopefully)

Tomic601 -what dont you like about your system ??????

 

Missing the upper treble response and crispiness. I feel the details are not fully revelled.  I am thinking this is the trade off  with fully tube amp and preamp.

Initially I had Devialet integrated hooked up to Focal N3, that definitely was not to my liking. After getting the Auris Tube Mono’s I like the laidback, warm rich sound . Wondering by changing the preamp will I be able to improve the highs.
