does it logical to invest on expensive transport?

at these days when we can use a laptop with a good DAC ,hi-rez files,is it logical to purchase an expensive transport?
as i understand the hi-rez files are more quality than a standard cd's.

thank you
I haven't tried a lot of the higher end transports but people I trust who are in the know, state that good transports are miles ahead of computer audio. Logical is a word I try to avoid in this hobby. But it would seem "logical" if one of the better transport manufacturers would attach a usb and/or fire wire input to accommodate a computer.

All they would need to do is bake in a nice usb/spdif converter. For the audiophile that wants to use both sources (me) this input would eliminate a digital cable ($$$) and streamline connections.
Explain "in the know"? If you download music from you take the transport out of the equation. So would people "in the know" still claim their transport is better then a computer based system?
OK. I guess I started this with the "in the know" comment.

First let me state that I'm all aboard the computer based source train. It's a blast and fits my listening lifestyle perfectly. I used to own a pretty good SACD player and curretnly own about 75 SACD's. At first I thought it was really superior to redbook but after some time I kept finding myself listening to "sounds" instead of music, so, I decided to go a different direction (non-upsampeling Audio Note DAC)... Just so you know where I'm coming from. This direction isn't for everyone and I will be the last to say my religion is superior to your religion.

Now, from a practical perspective. Most people I know own 1000's of CD"S. Replacing those at $30 a pop seems absurd. Especially with the first high rez download format that comes down the road. You have blueray looming large and then there's the argument about: are these high rez files really high rez or are they just upsampled? Let's just say I'm skeptical and probably the subject of another thread.

I don't know about you, but I have limited resources. I think Warren Buffet gets it right when he advises investors to get in when everyone is getting out and get out when everyone is getting in. Right now seems like a perfect time to pick up cheap CD collections. I see collections hit Craigslist at rate of about once a month for for a few bucks a piece. Therefore, a good transport which optimizes redbook for when I want to listen to that special recording from front to back, with a usb input for when I want to listen to play list, back ground music and internet radio is the perfect scenario for me.
Lokie, I have similar sentiments. Recent improvements in computer audio and availability of hi-res internet files are getting me interested. However after years of accumulating CDs and making refinements to a traditional RBCD front end, the question is when and how to assimilate these changes. I recently had a taste of the transport dilemma after installing a current-production ESS 32-bit 9018 Sabre chip in my SCD-1. The implementation allows toggling between the Sony DAC & digital filtering chips and the replacement ESS DAC combined chip, feeding into the same analog stage. Moreover I can swap between several transport sections that are in various states of modification affecting jitter. The ESS chip is supposed to be impervious to input jitter. However, the transport swaps suggest otherwise. So at least in this instance of a SOTA RBCD DAC, the quality of the transport still matters. Since the ESS chip supports universal data rates to 200kHz, it will be possible to gate its digital input to hi-res external files via USB, I2S, etc. However for silver discs this purportedly SOTA chip will continue to demand a high-quality transport.
