Bookshelf speakers with the good bass.

Save yourself a ton of $$$ and get the NHT Classic 3.
I had them in a room almost identical to yours using both tube and SS. They sound fantastic for the price and they have beacoupe bass.

Kiza I see you also have a post regarding possible speaker stand options/height. Rather than changing speakers ( I'm a fan of Harbeths , (I own the Monitor 30s) one idea that might be worth considering is something from Mapleshade's range of stands, the Bedrock or Gibraltar . The place the speakers much lower than normal and are suppose to increase the bass output. I've not tried them myself yet but if you want to avoid using a subwoofer, it might help.

Just curious as I always found it odd that when unless your "Bookshelf" speakers are actually on a bookshelf why would a floorstanding speaker not work that takes up the same space as a monitor on a stand 14 inches from the wall. This also removes the sub and with the proper choice in design (and size of the drivers and the tower ie) not rear ported or over pressurizing the room many can be placed closer to the wall than on a stand. You also get the bass thats lacking. Cheers!

I previously owned Dynaudio Special 25's. Their bass belies their size and appearance. However they are rear ported and perform best on stands and away from the wall. I now use Merlin TSM-mme speakers. These also have wonderful bass performance and are a top choice in a compact speaker. I was amazed at how good the bass lines are. I played Gary Karr's Spirituals and his Adagio discs and they sounded superb. Merlin's are worth auditioning and seeing if they will work for you. Merlin's are sealed in a cabinet that is as solid as a brick. They can work well as a bookshelf if needed.

Totem Mani-2 have incredible bass with weight and accuracy that I doubt you can match in another bookshelf speaker.
