Improvement in CD player transports

Have transports improved over the years the way DACs have? I have a Cary Audio Xciter DAC and have an Acurus CD player and a Music Hall CD 25.2. Not sure which to use as the transport. The Acurus is built like a tank and has the air constrained dampening, but the Music Hall is a lot more current component. Opinions are welcome. Rest of my system is on Audiogon. Upgraded to MartinLogan Electromotions and the PrimaLuna Dialogue 2 since it was posted. Thank you.
Of course the real answer is you have to do the hard work of plugging them in and listenign to both, comparing what you hear. I recently switched from an old Sony 707ES as a transport to a more recent Sony 777ES SACD (I think I've gotten the model # a bit mixed up, but you know what I mean) player and noticed an improvement.
Thanks. I am in the process of doing the comparative listening now. I just need to decide which sound I like better, as the older transport seems to sound more analog-like and since I am mostly into vinyl I kinda like that. Thank you again for your comment.
I would put my redoubtable CEC TL-1X (modded by RAM and updated by Nick Gowan at True Sounds)up against any current transport, without regard to price.

I would put a LINN Akurate DS playing 24/96 or 24/192 FLAC/WAV files against ANY CD player under $20k. Eliminate the CD itself and you eliminate a lot of the noise/jitter.
I’m getting excellent results using a OPPO BDT-101IC as my transport into an Ayre Codex DAC. I started with an old Sony DVD player back from the early 2000s that was made in Japan. The old player has character and the sound is decent but it lacks the ability to pick up any real details. It is fun to listen though, better than half the player I auditioned. My goal was to spend less than $500 dollars on a CD player/transport. I first tired the Okyno C-7030 and it wasn’t good at all, I returned it after one day. Then, I moved over to using a dedicated transport from Cambridge Audio CXC. The CXC sounded great, but it was a one trick pony and only played Redbook CDs. Also, there was no built-in DAC.

I never really considered OPPO as an option, since the only model I considered was the OPPO-105 which is about $1300 dollar, but when I saw the BDT-101IC Blu-ray transport player on their website, I decided to give it try (about $400 dollars for the two channel stereo model). It doesn’t have a toroidal power supply like the OPPO-105 or the ESS DAC chip, but the disc pickup mechanism are the same. It also includes an AKM DAC chip set, in case you wanted to connect it directly to your amp (a good option to have compared to the CXC), which in my view is as good as the Cirrus Logic DAC chip they put in the OPPO-103. Cheaper than the Cambridge Audio CXC and with the ability to play every disc and file types including SACD, FLAC, Blu-ray...etc, I’m very happy with this player as a transport. The added bonus is that in my view the appearance of the BDT-101IC is better than the OPPO-103 or 105. Note: If you call OPPO, you can order one directly from them, you don’t need to go to a custom installer as suggested on their website.

Sorry when on a tangent, going back to the original discussion. My advice is to try different the setups and pick the one you think sounds the best.  If you are looking for a modern player as a transport and you don't want to spend to too much money, give any OPPO player a try.  
The Acurus could very well have the better transport and deliver sonics closer to your liking however the only concern I would have is its’ age. Often the 1st thing to go on a CD player is the transport or the pickup lens. 

Never thought CD players worked well as transports. Bought a 47 Labs Flatfish Transport and had a guy modify it with a super clock, BG caps in the internal power supply, and runs off a custom battery and cap bank power supply. Cost a bit but was worth every penny! This is the cleanest most analog sounding transport I have ever listened to. This transport elevates every dac it's hooked up to. It is amazing how much information there is on a 16:44 CD! 
Sadly though I will be listing it to pay for some medical bills.
Cest La Vie,
I rarely now use a cd transport, come to think of it, even less Bluray / sacds as well.  It has all gone to digital streaming.  Once, complex mechanical designs were necessary to read data off a disc to reduce jitter/noise but now that can be accomplished with burst reading, reclocking, and tcxo's with low phase noise such as the Crystek 957.  Take a look inside Parasound's latest cd player - Halo CD 1.  It is a computer with a small analog out section.
