The wave has a single cd input, so you'd be changing disks often, if you don't utilize the SoundTouch programming and play from your computer, deezer, etc.

Using the aux unput for tv sound is okay, but you will need another cable to make it work. Depending on your TV output you will need either a 3.5mm to rca or a dual male 3.5mm

Following off p_devil, I'd go with the SoundLink over the wave. Portability and plays anything over the wave, which is a clock radio plus soundtouch, which includes bluetooth.

Really just a question if you're going to want to move your music away from your house (soundlink) or keep it at home (wave). If you pick the wave, give it like 2 minutes to re-establish the wifi connection before trying to play.

Here's the thing about audio. If it sounds good to you, and you can afford it, you win. If you're enjoying your music, you win. Yeah, XYZ setup will technically be better, but if what you have now works... rock on, friend.

Why am I seeing such varying prices online? I see some going got 89$, some for 300-400$ plus and some going for well over 1000-1500$ It has been discontinued. So some people are paying more than the retail price to get a pristine "new in box" system. While "Open box" systems appear to be selling for around or under retail price. What is the actual selling price for a good condition used (BOSE SOUNDWAVE 4 WITH PEDESTAL AND REMOTE.) It's called the Wave SoundTouch IV, no one really knows what the price is now. The only real idea would be to look at what others have sold it for using the eBay Sold Items listing. Some standard Wave IV's show up (no SoundTouch pedestal) in that listing as do broken ones, so be careful when judging prices. I want to make sure I'm making enough money off of selling this, don't want to undercut myself.. I have an offer for 200$, already. I will say that $200 does seem to be quite a fair bit under what others have sold it for. Even the pedestal alone has sold for more than that. It seems that most have sold between $400-$600, with a few reaching in the thousands. It all depends on the condition, information, & photos provided in the listing. More on reddit.com
