So my questions are:
1) will the receiver DACs give me just as good sound as the DACs on a good, dedicated single-disc CD player?
2) Will my receiver be technologically obsolete by the time I'm ready to actually make use of the home theatre-ness of it?
3) What would you recommend I do?
Thanks
1) Do some research on the net on the DAC chips used in receivers and players. There are good and bad DACs in either gear. Offhand I should say that the DAC on the NAD CD player C542 or a Rotel RCD1072, being HDCD capable, is an excellent one. If you had to invest on a CD-only player, get one with HDCD abilites. They have a digital filtering circuit that is superior to other non-HDCD players in the same price point and can benefit even regular CDs in terms of sonic quality. To check on this, find out more about HDCD (High Density CD) from a google search.
Having said that, it's also possible to get superior DAC performance with upsampling abilities from many mid-to-flagship receivers. You may not find one from entry level HT receivers though. A NAD, Harman Kardon or Rotel mid-priced receivers come to mind. You can then use entry level CD players from Pioneer and Yamaha or from any excellent brand that are known to exhibit respectable and stable transport qualities.
And since, as you said, you are not yet ready for a full pledged HT surround system, I'd rather use my funds to get the most out of a 2-channel system that you have. A good CD player is one road to go. It's also an option to invest in a good SACD or DVD-Audio player for you to enjoy the benefits of the new hi-resolution digital formats, even in stereo mode this early.
2) Entry level receivers with 5.1 or 6.1 identical amps may not be entirely future-proof, considering that most mid-to-flagship recievers out there are at least 7.1 channels. It is the digital processing and the video/audio input and output flexibilities that are subject to obsolescence in receivers. New video input features like progressive component inputs and digital DVI terminals and some with Firewire and i-link terminals should make a receiver a bit future-proof. Audio formats such as DPLIIx and DTS96/24, Neo, DD-EX, and DTS-ES should be around for the next 5 years or so. The promised SDDS from sony/columbia hasn't arrived yet in receivers so nothing to worry about that.
And this obsolescence factor is what's driving me and many audiophiles to go in the separates preamp and power amp route. There's always a chance that you have to get rid of the entire reciever if you begin to outgrow its digital processing and input flexibilities. Not so with power amplifiers. Power amplication has probably reached its technical perfection a good 20 years ago and will do its job 20 more years from now. How often do we encounter old Carver. McIntosh and Hafler amps of the 70s still going strong and will most likely be used for the next generation?
Modern HT preamps, OTH, with their digital processing features do get obsolete and can be upgraded separately.
If you can get the funds, you may want to upgrade your power amp separately. Your NAD integrated probably has pre-outs you can use for this purpose. Start with a good stereo power amp conservatively rated at least TWICE that of your NAD. But going for a lesser powered amp with better musical abilities is also an option. I 'd think of a Musical Fidelity, Rotel, Acurus, Aragon, Parasound, Adcom, to mention some.
There are excellent multi-channel power amps out there to start you off on your HT journey. Offhand I could think of the Rotel RMB-1066 which is a 6-channel power amp that can be bridged to deliver a more powerful 3-channel amp which you can use now for 2 channels only, unbridge it later for HT. There's also the Acurus and Aragon 5-channel power amps from which you can just use 2 channels in the meantime.
Then, the last part of your journey would be to get an HT preamp/processor either form Rotel, Krell, Aragon or Sunfire to mention some. Then get the complementary set of speakers to augment your paradigm pair for a complete 5.1 or 7.1 set-up. Don't forget a powered sub should you decide to need one.
Ofcourse, the idea of an all-in-one box such as an HT receiver can be compelling. After getting your CD-only player, I would suggest getting a NAD, Rotel, Harman Kardon or Arcam HT receivers. Likewise the Denons, Onkyos and Yamahas are excellent specimens if only for their digital processing excellence. Just my thoughts.
