amp/preamp for snell b minor

Hello all.

I am relatively new to the "audiophile" hobby and have a couple questions. I recently purchased a pair of snell b minor speakers and would like some advice. (Snell b minor - 8 ohm; 90 dB; rated 40 - 400 watts) I currently power these with a Jolida 202A tube amp delivering 40 watts of power (integrated amp). I have also used a Parasound Halo a21 delivering 250W of power but strongly prefer the Jolida tube sound - and have noticed a huge difference in volume with the power difference. I use a Benchmark DACpre as a preamp/dac in conjunction with the parasound.

In any case, although the sound with the Jolida is good, and at times wonderful, I feel that I am missing something in dynamic range and imaging. So, I am debating changing my amplification.

Liking the Jolida tube sound, I have considered purchasing the Jolida monoblocks which deliver 200W of tube power. I would also purchase a matching preamp.

I have been reading however about the "amazing" SET sound which I have never experienced and so am also looking at a pair of SET amps (Mingda) that deliver 40W of SET power with a matching preamp. The cost for either would be relatively equivalent.

My current listening room is relatively small and I listen to all forms of music including jazz, rock and symphonic and chamber classical music.

Do you have any advice?

Greatly looking forward to your help,

Eric.
