Amplifier recommendations for LSA-1 Signature

I used to be a purely HT guy - had definitive technology 7006 speakers and Onkyo mid-level receiver driving a 5.1 setup. One thing I did not like about DefTechs was how the music sounded, I just couldn't stand to listen for more than 15 minutes. Then I read about listener fatigue and the so-called 'musical' speakers, and started looking for a new set of speakers that were more musical than the deftechs. This led me to LSA-1 Signatures. Now, I don't consider myself an audiophile even by a long shot but I can tell you that these speakers are something special. I can listen to jazz, classical and semi-jazz like norah jones or melody gardot for hours at a stretch and never get tired of listening. For some reason the same speakers sound pretty mediocre when listening to rock or even soft rock.
However, I listened to another setup at a friend's house (he was using B&Ws paired with B&K) and the same music was suddenly even better than in my setup. I won't pretend to claim that I understand what people mean when they use terms like imaging or dynamic or transparent, but it sure sounded wonderful!
Now, I cannot afford B&Ws - at least the nice ones. I auditioned the ones they sell at Best Buy Magnolia but just didn't like them much. So I'm thinking I can probably stay with LSA's and use a separate amplifier in conjunction with my Onkyo (110 wpc).
So my first question: Is it even worth adding a new amplifier? I am not necessarily after more power as I listen at low to moderate volumes, but that magical sound that I heard at my friend's house - clean, tight base and even better separation than what I can get with my current setup - but at the same volume.
Secondly, I cannot afford to buy expensive gear at this time. So I'm looking for used equipment around $1200. I generally like the laid back, smooth sound of the LSAs but sometimes I do wish that they had a bit more sizzle and oomph but not too much like the Paradigms (sorry don't mean to start a flame here but that's how I felt when I listened to the Paradigm bookshelf - Studio 20).
Any recommendations?

Current setup:
Onkyo HT-RC180 (110 wpc)
LSA-1 Signature (Front LR)
Definitive Technology (Center; soon to be replaced by LSA center)
Definitive Technology SuperCube 1 (sub)
Definitive Technology (surrounds)

Short term goal:
Add a new amplifier to improve 'musicality' - even if its at the expense of HT sound

Long term goals:
Replace Onkyo with a better PrePro
Replace sub with REL

By all accounts, the LSA-1 sigs are pretty nice monitors. I have not
heard the speakers personally, but there have been enough threads
regarding this speaker that I don't think the lack of response to your
question means no one owns them. I think its because of the other
equipment, and where you are trying to go in a combined HT/2Channel
system for $1200. Also, you say nothing about what your source
component player is. Are you using a universal player?

The Onkyo is probably suspect with respect to the power amp and the
preamp section. If you weren't using this for HT, I might suggest you
go looking for a nice 2 channel integrated amp. You will probably
improve things somewhat by using the preamp out to a better power
amp, for instance a McCormack DNA 125, which you should be able to
pick up in that price range or less.
However, not knowing anything about your source, you might want to
pick up an Oppo 105 universal player. That might give you the biggest
improvement unless you already have a very good player. Then, you
will have 2 quality components, your source and your speakers, and
perhaps later down the road you can free up some more money to
address a better HT processor/power amp.
Your speakers go down to about 45Hz, which is pretty good for
monitors. I don't know anything about the dynamics of your speakers.
With a ribbon tweeter, you should be getting enough
"sizzle." Anything more is going to get you back into the
listener fatigue thing.

Arafiq, the Oppo has built in wireless and ethernet connectivity. Also, the Oppo 105 has pretty nice digital in capability (asynchronous USB an coaxial S/PDIF) and a very good DAC by all accounts. You should have no problem running your lossless files. However, if you intend to stick primarily with digital in from a computer rather than CDs, that may not be the best use of your money. Maybe a stand alone DAC would be worth a thought.

I think Everest shares my concern about the Onyko and using it preamp out into a better power amp. You will get some improvement, but the preamp section is still likely to be a limitation. The used integrated with HT bypass is worth thinking about.

Arrafiq, Your situation is a tough one, which is why I think you didn't get any responses initially.

I would make a couple of comments here about how I generally approach situations like yours. We have all started someplace, and dealt with budgetary limitations. You got a taste of what good equipment can do for you with your LSAs, and I would add that I think you made a wise purchase there. Those are speakers that you are going to be able to hold on to for a while, and as you put better equipment in the chain, they will continue to deliver for you. That is the correct model going forward. Sometimes, that means you delay purchase until you have enough available to get that next component that will push you to the next level. That can be frustrating, but it will avoid a lot of wasted money spent on making marginal improvements. Thinking about your situation, something like a ModWright integrated with built in DAC would be perfect, but it is way out of your price range, even used. I took a look for a used integrated for sale that would work for you and didn't see anything for sale right now.
The modwright stuff is superb in my opinion. Every once in a while one of the Modwright integrateds come up used, but I haven't seen any used ones with the built in DAC hit the market yet. This would be an option that would without question be worth waiting a while to procure.

I take it you are using the apple TV as your video source, so that you currently have no playback capability for DVDs or CDs, and it is your desire to continue with that set up going forward. Sorry if I am being dense, but I'm having a hard time wrapping my head around that. :)
Thinking about this more thoroughly, if I have all this right, I still thing the oppo 105 may be your best move if you are locked into $1200 at this time. You can still use your apple tv for video if you want, but you can use the much better DAC in the oppo to real advantage with music, it has wifi capability, and it also brings physical media capability into your system.
A DAC with USB capability may still make sense, but you have to provide for connection to your digital files, which may or may not be practical. It seems to me that the Oppo circumvents all of that and you get a good dac along with all the rest it gives you.

Arafiq, I really think you are going to get a nice improvement in sound with the Oppo. I use my older Oppo 93 in my HT and the audio is much better than with other players I have used. Its one of those nice pieces that you will be able to hand on to for a while as you continue to build your system.

Arafiq, I read the stereophile review on the HK990 suggested above. I have no familiarity with this piece, but it got a very nice review and was used with some pretty nice equipment. My guess is this is a pretty good recommendation.
I also have no familiarity with your Onyoko. My guess is the apple tv is the weakest link. If it were me, I think I would still go with the OPPO upgrade first, but its really just a guess. I have about a 50% chance of being right.

Arafiq, I think eventually getting both of the pieces would be a good idea. Which ever one you do first, I would try to get the apple tv out of the music and use it for video only. An ethernet or WiFi transfer of your music files (hopefully wav, flac, or apple lossless) to the DAC, whether that be the oppo or the HK, seems better to me. The apple tv is great for what it does, but, it's a $99 piece. You can only expect so much. However, if this set up is working well for Manoterror, maybe you should go with the HK first and see if it gets you where you want to be. If it works, it will make the wait for the oppo a little easier.

We have all been infected by the same disease here. But patience is always our friend on this stuff. Hard as it may be.
