The main component in CD playback is the DAC which is going to digest the 1's and 0's and transfer that data into analog. The Main function of the CD Transport is the pick-up laser which picks up what is written on the Disc ,the motor mech to spin the CD and the most important part IMO is the DAC is the sampling rate and error correction it has and compensation of the Jitter.
high-quality CD transportsÂreduce jitterÂimprove soundstage depth and low-level resolution, contributing to a sense of spaciousness.
It's still a very mind blowing thing what a CDP does,but the quality of those players have gone from bad to worst due to Compression and the GIANT's of industry cutting cost by incorporating everything on the smallest chip Supercomputers can come up with leaving we the diggers of buried treasure searching for the Best transports from days gone by or else spending Zillions to perhaps get to what is as close to CD Nirvana we can afford.
I'd rather have a Grade "A" Transport and forget about that equation for years and test as many DAC's as possible,I still do not know where the Cabling comes onto it as I tend to believe one Optical Cable is not going to differ than another due to the fact that those 1's and 0's due not differ once they have been through the DAC stage. There is no variable I see to contend with after it has gone through that stage,but Cable's will make a big diff when they are dealing with analog signals .
For those who do not think cables make a diff I put forth the scenario that all equipment has a sensitivity just like Digital recordings had when they first went from Vinyl to Silver Platter. Another words if your system(esp.Spkrs.)are sensitive to changes then when you intro something new then it shall have a tonal effect for better or worst.
If your not looking for sensitive equiptment stay with lower graded mass produced Craig,Fisher etc. stuff. I use to tell people that were gonna spend $3K on Car Audio take a CD and Record it onto a Cassette then get into the car and have your girl or whoever change back and forth.You won't be able to tell the diff. Now that does not go for components such as a top of the line player and speakers,but recording and spending to much on Car Audio you can get away with
Another thing is Bass Cables.You don't need Garden Hose to transfer the easiest signal in the Audio spectrum to re-create Bass.You'd need larger cable if you were sending the signal longer than say 5ft..Monster sure is making enough off the fallacy along with BOSE and their bunk idea's.I'll buy a KLH system and save $1000 Thanks,but we all need to feed the dream.
Ag wire cables also don't need cost $1000\ft. to get some really great sound. I am not in the Biz right now so I am just sharing and I hope good things for those little manfactures who sell a good product for an affordable price and the giants who sometimes create a great product to.
Back to CD Redbook Players
I have an old Phillips which can't seem to misread CD's ,but I use an external DAC which is more modern and can translate the 1's and 0's better when translating it into analog.
By the time your 50k DAC reaches your door it is obsolete due to the parts and topology structures figured out by engineers and the latest tools used to create CD Playback. Better components and smarter circuitry along with isolation of what is being read such as .cda
To answer your question "NO"! Separates are best for several reasons and Transports are not a thing if the past IMO. Look at the leading manufactures like Ayre and newer cos. like Shiitz who I bet would not have a good biz if it were not for those who want and can afford the best for their Biz and Hobby.
parameters measured include data error rates, ability to correct (rather than conceal) data errors, and jitter. All are being overcome with each incremental step taken by designers. The closer they come to absolute 0 readings the closer we get to perfection.SO much is being done in the way of Caps, Resistors, Transformers, PS. Designers using high grade parts with Mil tolerances is what I have to see
I cannot believe how many people can be satisfied with mass market DVD Player which incorporate Chips which use the compression of MP3 and make the average buyer lose out on what CD Redbook has along with so-called CD's which were not Re-Mastered into quality Digital formatting. There are artist who go through their catalog and seek out the finest engineers to transfer the Analog tapes into HD Sound. Look at the Supergoups who did it and the Old Classical Recordings which really sound like orchestra's playing under the sea.
In the end it comes down to the Recording Mastering-Separate Units to recreate the sound into analog.
It is best to purchase the Best Transport then every couple of years upgrade the DAC IMO. Lastly I will add synergy between components.
The most sensitive system I ever put together involved using a Passive Preamp as it was and still is a great way of testing individual Cables and audio equipment. I am thinking of getting another system together using one.The BIG downsides is if the Recording is Bad it shall be there in all it's nakedness and finding the right synergy of upstream components.
Hope that helps and hope my memory is right in components in the Audio community. And some of my best friends still love BOSE so I do not leave the room when listening to their components I just smile and laugh at what they have to say as I still love my old Pinto and I can fit more people in it then a Linclon. It can out run a Porsche also when the Porsche has the engine out for an overhaul.
I recently saw a set of say 22ga. Ag wire put in normal Clear Tubing with the asking price $700 I think which is sad as I tried so many different designs and tested many along with exotic plating and Metals until I struck upon combinations which were worthy of being brought to market or which I felt proud of what I produced, One leading manf, could not tell me the difference in the Bells tolls at the 1812 overture as in my testing there are certain recordings I use as Audible Benchmarks.
Many favorite recordings like David Gilmore's Solo LP had a distinct chord and it is really hard for a system to catch each individual chord being struck and not having it muddled.
So when looking for the best make certain it performs particular challengers to what you listen to and measurement are not the whole story.
An example was having a great Krell Intergrated did not work well with my Reference Speakers,but their Monoblocks and Dual Channel Amps did.
When I start my next co, I want to have as many types of speakers along with differing Electronics to watch for synergy condition which may come about.
I look forward to the challenges I once over came and the positive reactions I had by those who owned what I developed. This time I want everything right. Everything made in house including the Connectors.
Good Luck!
