What to upgrade next.


This is my first foray into the forum other than reading other's post. I hope respondents will be kind! I am at the very low end of audiophile equipment and many of you may not think I am there yet when I list my equipment. The economy has become better for myself and I am looking to upgrade but not exactly sure where to go from here. I am sure I will receive many different suggestions so I plan on taking the one suggestion that I receive the most and employing it. My equipment is as follows: Denon AVRx 3500H as my integrated amp which is boosted by a Bob Carver Cinema Grand 5 which pushes 200wpc. This powers my Polk Audio RTiA7's which are my music floorstanders. When I started upgrading I chose the Polk's as they seem to punch above their weight. After months on this site I am unaware of many people who extol the virtues of the Polks so I am thinking this may receive the most as far as recommendations. I stream most of my music from my desktop and laptop. The desktop sounds like an airplane waiting to take off. I am not independently wealthy but am looking to spend between 2-3 thousand if necessary. The one thing that gives me the biggest headache at this point is music delivery as computers have glitches and my angina acts up when the music cuts out in the middle of Alex Lifeson shredding his axe. My music files range from bad copies of MP3s which are slowly being replaced to HD Audio files. Thank you for any suggestions.

I take it you like your speakers. I suggest you upgrade your source and also replace the Denon AVR and and possibly the amplifier. That would improve what you are getting from them.

I would start with the purchase of a streamer. The Bluesound Node is within budget. They run $500. The internal DAC is OK, however many replace it with an external DAC of choice.  This you could also consider after getting familiar with the Node.

The 1st question I have, are we talking about a 2 channel system for music?. I believe your Denon and Carver amp are meant for theater use. If so, I would consider selling both the Denon and Carver and purchasing an 2-channel integrated amplifier. An integrated is much easier on the budget than separates. However, you could also just replace the Denon with a preamp and continue to use the Carver amp if it works well with your speakers.

There are many threads here on AG concerning streamers, many specific to the Node, as well as integrated amplifiers. I would be inclined to search these threads.  I would recommend considering the the used market for amplification.  

Good luck in your quest.

 
I agree with @mesch -- if you like your speakers, changing amps, or at least introducing a better preamp, would be very effective. And, as others posted, all of *those* choices depend on your goals and preferences. Ends first, then means.
@flrun I use it for both but and want to keep the ability to do both but I love music more and would sacrifice on the home theater side. I have two handicaps that I am willing to overcome with a little help from my friends. The first is this- While looking to break into audiophile class it is on a limited budget. Ultimately I'm hoping in the $10K range at the end system. I know from the used equipment sites and the forums this is barely floor level for a single component but alas! I am but a poor man! The second handicap and perhaps the most detrimental is I am a caveman when it comes to a lot of the newer technology. I am streaming using HEOS from my desktop and laptop, wireless. I am slowly replacing mp3s with downloaded FLAC files and when I can afford it I replace special albums with 192 kHz 24 bit albums which I also download.
@mesch  I do not know if I like my speakers or not. I know for me they are the best I have owned but I know they aren't the greatest either. As with anything when you've had good and good isn't good enough anymore! The amplifier at this point I think I am happy with but willing to be taught if not as long as I can understand where I'm losing anything with the Carver. It is by all accounts a well reviewed and well performing. As far as my Denon I'm all ears as to why I should upgrade. If the Carver is supplying the juice when I am 2.1 or 5.1 then doesn't the Denon act as a pre amp and basically tell what to do what? I have but a child's understanding of these things. What would an upgrade in a pre-amp benefit me? I will definitely have to research the streamer recommendation. It is just out of my field of knowledge exactly what they are as I thought it was basically a computer program that allowed me to share to another device. If at this time I was going to spend the money on one component what would you suggest? Obviously getting the music supplied to the system in the best manner is of utmost importance but it sounds as though I wouldn't have to drop 2-3k to resolve that. Thanks!
@hilde45 While the idea of addressing three or four issues with one fell swoop has it’s appeal I think in the long run I may be repeating the process again in the future if I divvy up the money in such a manner. I am willing to admit I might be wrong however! Does it make more sense to spend 2-3k on a single fairly good component or have three mediocre components that I will have to upgrade again in short order?
