Since you asked for comments on our rigs, I'll add some here. As said, I'm bringing my complete 5.1 system, unless I find it won't all fit in the truck~
I'm including price paid, not to brag, but to give an idea what you could expect to spend for a similar rig (2007 prices).
Sony Generic Multi-disc Player: not more than one disc, but rather it plays many types of discs. I use it primarily for SACD/DVD-A playback. Purchased at Best Buy in 2008 for about $120.
Carver SD/A-360 CDP: An inexpensive cdp I purchased new (demo) in the Incirlik Air Base exchange for only $100. Had to break out the soldering iron once a couple of years ago to repair broken joints on the TOSLINK connection, but other than that & the occasional lens cleaning, has served me well over the past 14 years.
Benchmark DAC 1 digital-to-analog converter: Purchased new from Benchmark online in 2007 for the princely sum of $1,195. One of the only new audio components I've ever purchased. Bought it after hearing Dreamer's DAC 1 at CF2007. Incredibly clean & detailed.
Sunfire TG-IV Pre-pro: purchased used on eBay ($1,950) in early 2007 as a replacement to a Sunfire Tube preamp (wanted surround capability, couldn't afford both) which I sold to forum member mikeg. A fantastic processor that has become a real sleeper on the used market. You can get impressive 2 channel with the "stereo direct" function...it bypasses all the processor functions (as does the 8-channel analog). I love the versatility of it.
Sunfire Cinema Grand Signature Seven Power Amplifier: Purchased used on eBay ($2,350) about the same time as the TG-IV to replace the 300x2 I sold to forum member mikeg. One of the most versatile & powerful amps I've ever experienced. Probably the most versatile amp on the planet. There are not many speakers you couldn't destroy with it....but it's more than brute strength. It has finesse & digs DEEP. The sound/power would be difficult to approach without spending many times the price.
Ashly XR-1001 Active Crossover: Purchased used on eBay in 2010 for $135. it was an exceptionally clean unit, & I was/am totally impressed with how clear & uncolored it sounds, & how low the noise floor is. I highly recommend Ashly based on this unit. The only drawback is there is no delay/phase adjustment between channels.
Rane PEQ-15 Parametric Equalizers: Purchased TWO units used on eBay around the same time I bought the Ashly, for only $125 for the PAIR, sequential serial numbers. They had spent their life in a single rack with little use. VERY clean units. I was a little disappointed with the highish noise floor, but I have a plan in the works to do some mods to make them a little more silent. In their defense, the manual states (& I've verified) the noise/hiss level is GREATLY affected by where the dials sit....the closer to center, the less noise. The more/less gain and/or smaller notch you dial in, the more noise that's added. I don't think I'd EVER buy a regular graphic equalizer after using these--they are very versatile. Basically, a parametric EQ allows much more precise, detailed control as you can adjust not only the boost/cut, but also the center frequency & width of the frequencies affected.
Carver AL-III loudspeakers: Purchased (eBay again!) in 1997 for $850. I paid premium price as they were in near-perfect condition with VERY little use. Drove all the way to Illinois to pick them up, wrapped them lovingly in foam, bubble wrap, & plastic for the trip home THROUGH A SNOW STORM (!). They were stained in "Pickled Oak" when I purchased them (the original Honey Oak is visible along the bottom edge of the wings). I've highly modified them in the past few years, including replacing the original woofers with Infinity Perfect 10.1 woofers & removing the passive crossovers (hence the active crossover above) & replacing the rear panel with high quality stainless steel. I also replaced the binding posts & fuse holders.
Klipsch RT-12d Powered/Active Subwoofer: I purchased an entire Klipsch RF-83 surround system NEW in 2007 & ended up selling all but the sub last year to fund an attorney to fight the ex. It's a great sub in the sub-$2k bracket. I cross over at 40 hz; everything above that goes to the AL-IIIs. You can get better, but for an 850-watt powered sub with active EQ built in, it's not too shabby. At 85 lbs, it's a lightweight in the sub category~
