In need of some Amplifier advice. Is therereally any point in it with my current setup?


Hello. I have posted in the past, but have since learned a little bit more from reading audio forums, and doing some research and have come to somewhat of a juncture. 

I figure I could "stair step" up on my own and enjoy the ride, or, ask those who have most likely been where i am before and skip a few steps =). 

My current setup consists of a Yamaha adventage-A3070 AV receiver (150wattsx8ohms 2chd), and 2 Polk LSIM707 towers. 

I've been looking at used Classe amps here on audiogon, or possibly a new parasound Halo A21 power aplifier,  and have thought about purchasing them. 

My question is, would my Yamaha advantage 3070 even be a sufficient pre-amp? It has pre-outs for all channels, and it also has an ess sabre DAC for my digital flac files. Or would using the Yamaha as a pre completely destroy the sound of the power amplifier? Essentially wasting $1,000-$3,000. 

My other question is pretty obvious. Should I trade up, just spend the $1,000-$3,000 on better set of speakers I've been eye balling like  the EMT-LFT8s, and stick with the Yamaha receiver's power for now. 

If it were you. What would you do?

I was inclined to agree from the beginning with essentially starting over. And  in a post above i mentioned the probability of buying a different set of speakers and an amp. Adding a matching preamp to the setup will be just fine. 

As far as the preouts and loop in/loop outs go I have a fairly good understanding of it and that won't be an issue. 

The other thing I've thought about, which @2psyop  mentioned, is, speakers for different purposes. 

The Yamaha Adventage 3070A has so many various decoding modes for home theater and surround type setups its ridiculous. small/large center presence for L/R. small/large surround presence for L/R. Ref SUBw presence for L/R, that I really dont need a full surround system with the Polk 707s. The Ref SUBw presence is enough to shake my house with the 707s. and the small surround and center on the polk 707s also do the job. They actually do make it sound like most of the surround coded audio is coming directly from the left or right of me. So overall, I'm happy with this for home theater. I'd add the 706 center or the 703s for surround but this would obviously sap too much power and strain the receiver and probably just weaken the bass and overall system and I would need to get it it's own 5 channel amp. Which I don't want to do. 

I may keep the 707s and AVR for this home theater setup.

When I want to listen to music, simply move some a few interconnects and banana plugs around and hello new music 2.0 setup!

I really appreciate everyone's input and posts on this. And I think I've learned there is no need to try and cheat or cheapen my way around it like @soix mentioned with an AVR preamp setup baha. 

I will be trialing new speakers, and then looking into pairing a pre amp/amp after finding a pair of speakers that sing to me. Maybe it'll be harbeths, maybe it'll be EMTs, who knows. Let the fun begin!
@mtrot  I actually was not aware. I don't think I got your message. I know there is a company called audio dimensions in Oklahoma city but their ratings are very poor, and I have a few friends that have been there and I hear it's not a company you want to visit or work with. They essentially push one set of home theater speakers on you with amps they need to sell and don't really let you demo much. 
Hmmm.  @moskaudio, you do realize the setup I described above allows you to keep the AVR and pure stereo components (amp and preamp) completely separate within the same system without having to swap any interconnects or cables, right?  That's the whole point of this.  If you're having to swap wires to switch between stereo and HT there's something amiss here.  All that's necessary in the setup I described is to change the input on the stereo preamp to switch between the stereo and HT, and you'd be using your "good" speakers (when you get them) for both stereo and HT.  No 707s required.  The AVR is completely out of the system for stereo and only involved when doing video related stuff -- nothing cheap about this at all.  Not sure I was clear on this point. 

@OP, that is definitely not a dealer you want to deal with.
If you can make some time available, take a day or weekend and contact a few dealers in Dallas. Make sure they can accommodate you (if they can't, scratch them). Tell them you are listening to find speakers you like and don't worry about details-like amps/pre/source. Just let your ears be the judge.
A good dealer will be happy to let you audition and not pressure you.

For the message I sent, you first have to go to the main Audiogon page and navigate to your name/profile box in the upper right corner, where there will be a drop down list of options.  Select "Dasboard", then "Inbox".  Then my message should appear.

Also, I agree with soix above that there is no need for switching cables; you just get a pre-amp or integrated amp with home theater bypass.  I am currently researching this and looking at various pre-amps and integrated amps.
