NAIM 72/180, Nait5i vs KRELL 300iL

Hi All,
I am on the market for new/used SS amplifier in the $ 1200 – 1500 price range.
Since I am from Bulgaria where the choice are quite limited and after auditioning some low priced Rotel, Arcam and Denon stuff and PrimaLuna One&Two from the tubes I narrowed my search to two brands – NAIM and Krell (UK vs USA :) )
I got lucky to find in my price a 7+ years old olive Naim 72/180 combo and I really liked what I heard from my speakers.
What I am not sure, and need your help here, is will an used Krell KAV 300iL be the better choice – more excitement, more bass ?
The problem is I NEVER auditioned Krell and there is NO way to do it prior my purchase!
I like NAIM but will I enjoy Krell more?
So, here are my possibilities:
- NAIM NAC 72/NAP 180, pre/power combo – used
- NAIM Nait5i, integrated – new
- Krell KAV 300iL, integrated – used
I know there are thousands other possibilities but not here…
My speakers are quite easy load – Tannoy System DMT MkII 15” Dual Concentric, 98dB sensitivity, 8 Om.
I like rock, jazz-rock, acid jazz, electronica.
Thanks,
Ivo
