Are DACS necessary?

I am not a seasoned audiophile, but doing my best to put together a system that sounds great- on a budget. I have an Oppo BDP-83 Blu-ray player, a Marantz SR7000 receiver, a VortexBox Appliance for streaming FLAC files to a Logitech Duet, which outputs to the Marantz. I am looking into a DAC to increase sound quality from digital files, but have also started thinking about, down the road, investing in a good pre-amp and separate amplifier. If I buy a DAC now, will it eventually be redundant if I get a good pre-amp? Is there any reason why a good quality pre-amp would not include a high quality DAC? (Thinking along the lines of Marantz or perhaps Integra separates). Knowing my budget overall is very limited, I am not shooting for the stars here- just solid sound to my infant ears. I would hate to buy a DAC now only to find I have no need for it next year. Any thoughts or suggestions are most appreciated. Thank you.

Bsoz - I'm using Benchmark DAC1 as a pre since I don't have analog sources - otherwise I would find DAC with preamp like Benchmark DAC1 PRE. Using DAC as a preamp eliminates one set of interconnects.

An outboard DAC will very probably improve audio playback from your Oppo. It will not cramp your style if you move to conventional separates later. When you did, you would only have to resell your DAC if you specially wanted to use an (unusual) preamp with a built-in DAC, or a DAC-with-preamp like the Benchmark or the (discontinued) Apogee Mini-DAC.

You will have to factor a good digital cable into the purchase. Make sure it is 1.5m long.

The BDP-83 has a good built-in DAC. The SE version is said to be particularly good with audio playback. If you had the SE I would suspect you needed to get quite a good (i.e. expensive) DAC to better the built-in one. With the standard 83, perhaps you'd need to spend less to get a nice improvement.

I've been using a Muse non-oversampling DAC with my Oppo 981. It makes a nice improvement and was not expensive. The 981 is not the BDP-83 but on the basis of my experience I suspect that even one of the lower-priced NOS DACs like the Valab might do something nice for you.

You can also get your Oppo's DAC modded with the other usual circuit improvements and superclock to better your sound from a one box solution. Again it will most likely not interfere with conventional preamps which normally don't have a built in DACs.
