Just getting started on a budget and need bookshelf speakers/receiver now


I am poor and need some bookshelf speakers and a receiver, all for around $600-$700.  I know this is a surely a travesty for most of you because you are professionals, but... I have to start somewhere and won't come into much more money anytime soon.  I currently have Infinity Reference 2000-3 speakers and a Yamaha RX-395 receiver.  I listen to CLASSICAL music and OPERA.  I'd like to have the speakers and a receiver that can handle bluetooth, my cd player, the tv and computer.  I've looked at Kanto YU6, Cambridge Audio SX-60, ELAC Uni-Fi UB5 and MartinLogan Motion LX16.  But I don't know if these speakers are better than what I've got (I have to think they are since mine are ancient).  I know you will probably say "just save your money," but that won't work.  Can you please help me?

Get the Elac UB-5's! Superb 3-way speaker designed by famed Brit Steve Jones (TAD). There is a pair now available on EBay for $408.91 (free shipping) from seller "savarety-official-store". That is about $100 less than the other sellers!
Add the NAD 3020 V2 and you will have a killer combination! There is a brand-new one in an unopened box available now on EBay for $400 (free shipping) from seller "singledadsunited".This has a phono stage and DAC! And is Bluetooth ready!
UB-5 + NAD 3020 V2 = $800. Well within your budget! This is what I would buy for myself if I had a limited amount to spend!
@schwantner: I have given the OP the BEST possible combination for his budget! Your lengthy post is just plain over-thinking! A common problem with others on this site!
