A little help please


My room is 13' x 21' x 8.5' ceiling. Speakers are located along the short wall about 12-18" off the wall. They can't come out as they'll block an entrance way.  They are about 4' from the side walls. 

Currently I have a Prima Luna Classic Integrated with their standard tubes. Source is Rega Apollo R, MMF-5/Clear Audio Nano V2, or Proton DAC. Speakers are Totem Arro (no mass laoding).

I realize that my placement isn't ideal and my wife's need for decorating balance with furnishings,etc require some trade-offs but I just don't think these speakers are up for the job in some cases. Some songs, like acoustic blues, female vocals, even piano sound great but I'm sometimes finding other recordings seem to sound muddy and there's no real pop and umf on some drums; like I'm hearing music but not feeling it some times.

The totems are not mass loaded. I have heard that mass loading them will tighten up the bass. I could also try some different tubes, but overall I'm not sure either or both will make that big a difference. Which leads me to a discussion of a sub or some new speakers.

I lean towards new speakers.

Possibilities (depending on what I can get my wife to agree to in price and size) are:

PSB Imagine T2, Quad 25L, Revel F206 - As noted above there are decorating issues. A sofa is located about 2.5 feet in front of the right side. As it is now imaging is good, my concern with these is they all have some low driver positions that will be an issue unless I can relocate. Relocating to the long wall is an issue because I'd have to straddle a working fireplace as well as other considerations. 

A larger Totem Forest - leaves me wondering if I'll have similar issues with bass.

Audio Physic Tempo 25 (NOT the plus version) - demo from my local store.

Vandersteen 3A - Signature - also demo from my local store. These are likely too big for my wife's taste; and quite possibly my amp.

 
 One thing I didn't note so far was the possibility of a sub-woofer.  I'm not thrilled with the idea but I haven't given it an ear so I can't say.

Thoughts anyone?

Thanks for reading and taking the time to respond, Jetson.

Here is another options pieced together.

The sig 2 with  a Demo Cary CAD-120S MkII for $3900 and as yet undetermined Pre-amp.  Keeps the tubes and leaves me with a path forward towards the Quad or other speaker in the future.

Like I said, I'll know more tomorrow.
Ayre / Vandersteen is a great combination - my 3A Sigs are matched with an Ayre AX-5 Twenty. The dealer loaned me an AX-7e integrated amp while my amp was being updated and I thought it sounded wonderful - powerful enough for movies and refined enough for music. Hopefully you'll be able to audition them together before you make any decisions.
Totem Hawk and Revel F208 are both real nice sounding speakers.  Your wife might like the size of the hawk better than the F208's.  I love the sound on both.  
I knew you'd love the Vandersteens and that Rotel is a great mate for them.  You'll love your music all over again!  I'd have loved to sell you my Treo's before I upgrade, but you'll be very happy getting yours and having them set up by Johnny who's as good as anyone not named Richard, lol.  
Beware - long post.

I first listened to the 2's and a pair of quatro ct through an Aesthetix Atlas and unknown preamp.  Wow - the speakers are capable of some amazing sound reproduction; at least to my 54 year old ears.  

After getting an idea of differences in the two speakers and what they were capable of, I listened to them both again, but through a Rotel 1570 integrated. An inexpensive SS amp. It sounded pretty good on both again - nowhere near the Atlas of course, but pretty decent sound. it seemed like the 1570 and 2's were a winning combination within the budget. But do I really need the amp? And I like the sound of this amp.  Isn't it a speaker problem was the unasked question still in my mind.  I hooked up the PL Classic amp. It also sounded pretty nice.... until input level got pretty high, then, to me it was clear, the Rotel sounded better. 

I'm no audio expert, but after going through it all it seems like it was two different things causing me issues; one limitation - the speaker - you can only get so much bass from a 4.5" woofer. And two - the amp - it isn't so much that the PL couldn't drive the Totems', it was that the Pl can't pass the signal without compressing it at some points, and that's what I was hearing. Is that the same thing - i don't think so. One is power, the other is bandwidth. So even with the "easier to drive" Vandersteens, the PL just didn't keep up when it needed to pass a lot of information. I'm not sure if I'm right or wrong - but that's how I understand it.

All in all John Rutan at Audio Connection in Verona, NJ spent about 4 hours with me, and sent me home with the amp and a pair of used Vendersteen 2's without bases, both for immediate enjoyment, and to make sure my wife was able to make the adjustment from the small presence of the Totem Arro to the much larger Vandersteens in her living room. Convincing her to remove furnishings to put in big, black boxes wasn't easy, but I was convinced she would feel so much better when she heard the new sound that she'd look past the redecoration. So I set the speakers on the floor in an approximate position, figureing I would work detailed placement out later, and ran the cable. She picked Lenny Kravitz, so I loaded the CD, and hit play, waiting to see her reaction. Then all we hear is terrible sound. If terrible is an exaggeration it isn't a big one. I mean, something was wrong, really wrong. WTF happened I thought? Did I mis-wire something? Nope. Is something wrong with the speakers? Maybe - they're a used pair I had not heard. Do I have a difficult room? Maybe, but could it be that bad? My ignorance was obvious and I needed to get John involved.

So Monday morning I called John from my office. After making sure I had not messed up polarity, he asked me about tilting the speakers and position. Tilting - nope, they're on the floor. Position - could it make as big a difference as I was hearing? I wouldn't think so, but I don't know. That's why I'm calling.

I guess I sounded so, because John seemed really concerned that I was freaked. He seemed more worried about it than I was - and he probably was - because I knew he would take care of it, and that in the end it would work out. He had a demo that morning and said he'd drive the half hour or so to my house later in the afternoon.

He arrived a little before me. When I walked in the back door, just a scant 10 minutes later, I knew we were a lot closer to where we were before. He simply tilted and repositioned the speakers, moving them closer to the side walls. I was amazed that so little did so much. We listened to some different tracks and also swapped between my listening to the Rotel passing analog and digital output from my Rega Apollo R.

The digital gives a bit more resolution and finer detail. The real surprise for me, was the difference in sibilance that was there with Kimber Kables, and not there with some solid core Audio Quest cables John brought along.

Then we set about doing a roughly measured, but accurately leveled and pointed placement of the speakers. It sounds really good right now. I'm so grateful to John, who turned out to be exactly the kind of audio resource the world needs more of - an helpful guy, passionate about sound, and honest enough to work a plan UNDER budget, knowing he'll have a dedicated customer over the long haul. I know I sound like a shill, but he deserves the praise.

Now, I'm looking forward to the new Signature series speakers, and the amp breaking in. There is also a bit of boomy bass in one small band, but I'm sure John will correct that when he installs the pair I bought.

Next is to figure out what Audio Quest cables I should consider - ones that will go with something like the Aesthetix Atlas, or perhaps some Quicksilver Monoblocks that will keep freediver happy.

Thanks for everyone's help so far.
