Hi all
Need some advise. I am currently running a pair of SongTowers, together with Emotiva UMC1 and XPA-3 (using only 2 of the 3 channels). UMC1 to me is already a marked improvement compared to my previous denon avr.
My hands feel itchy, and i feel like upgrading again 
Which do you guys think will improve the sound more? Power amp or adding a pre?
Any good options which will have more significant improvement based on my current gears?
Everyone's experience will be different depending on what the weakest link was in their system before upgrading.
For me, moving from the Wyred4Sound integrated to their separates (STP-SE preamp and SX-1000 monoblocks) was a very good improvement to natural, effortless resolution, instrument separation, and musicality and detail in the bass. I found the Van Alstine AvaStar and 550 Double Ultra to be equally resolving but to be missing the natural presentation and wonderful timbre that the Wyred4Sound separates provide. The STP-SE preamp is also a lot more convenient and flexible and everything runs cool.
This change was in the context of already owning a pair of HT1-TLs and a fine-tuned Mac Mini/Tranquility DAC front end. Everyone who's heard the Tranquility seems to report that it betters other things in the price range that they compare it to. For me it was clearly better than the PS Audio DLIII with level 3 Cullen mods that it replaced.
So, I'm sure you'll get a lot more data from other perspectives, but I vote preamp (and DAC possibly).
Happy listening!
