Audio Research Ref: CD8


I understand from speaking to Audio Research there is a CD8 now. CD8 has an upgraded power supply and DAC from the CD7. I have my CD7 at ARC for the power supply upgrade now.

Does anyone know more about the CD8?

Jim I enjoyed the rambling.

I dont want to rob this thread too much more, but there are some things that I think cause some people to prefer the idea of analogue.

1 its what many have grown up with and are used to.

2 Analogue equipment has on the whole a sympathetic way of coloring music. Digital has not.

Put both well sorted out studio systems against each other and you will find a mixture of digital and analogue will be best.

Try bouncing tracks in the analogue domain. Its a joke, and very lossy. In the bad old days you would then have to re EQ to bring the life back into the bounce bringing even more noise and signal path. Bouncing digitally you wont be able to tell the difference.

Digital can be lifeless and crunchy. It can also be utterly breathtaking.

Regarding the recording techniques like using auto tune and so on. Again this is a tool which speeds up the recording process and can be used well or just turned off!

Years ago producers spent weeks on vocals dropping in words and so on to fine tune a take. There is no money in the music industry anymore. Not like it was, so the process of making the product has changed. I can promise you, no one in it would go back though, apart from for the budgets.

In the beginning we were sold that digital was perfect when it was not. Now it is different, although people are still judging it by talking about out of date equipment and software. I hear lots of people trashing digital and then when you ask what they are using, its some rubbish 10 years old or even older.

Regarding the upsampling or non upsampling debate, I think it is all about implementation. You just have to find the right player (maybe the ARC CD8... See what i did there?!). DACs are much better now and the understanding of what the problems and solutions are is clearer.

My hifi source uses DSD, and upsamples red book CDs to DSD. It is astonishing. Whatever you listen for.

Now I must apologize for my rambling. Happy listening.
All,

This is turning out to be quite a lively and interesting discussion/debate.

My CD7 shipped from ARC last Wednesday, so hopefully I see it mid-end of this week.
I will report on the sonic differences when the unit returns.

The cost of the upgrade/modification was $100. I can't comment nor be quoted to ARC as "the cost", but that was the charge to me.
The mod involves replacing the 2 of the 3 6H30 tubes in the power supply (the ones side by side providing regulation) with a 5881. (5881 is a more "industrial" 6L6).
The 3rd 6H30 in the power supply section remains.

ARC also brought everything in the unit up to spec. ie. My unit turned on by itself when plugged in. (not suppose to do that). They also performed a full lab, and listening test.

I think it was a very good unit before this upgrade/mod. I suspect it will sound better when it returns.

I have had or listened to Krell 505, krell Ref64 with MD10, Rega. The CD7 with regard to high frequency transparency, lack of edge, and midrange detail bettered all of the above.
The Ref64 with MD10, is still in my opinion an incredible combination, wish I did not sell.
But I still think overall for musical enjoyment the CD7 is quite a bit better.
Will the CD8 have any digital inputs, such as USB? Would be a real shame if it didn't.
Wsill, my CD7 also turns on when plugged in....never thought too much about it
since I rarely unplug it. Very curious to read your comments on the update. As
I previously indicated, Leonard at ARC told me the upgrade was more for
stabilizing the regulation than actual sonics. I certainly plan on comparing the
CD7 with the new 8 when it arrives-and breaks in-at my dealer. The Krell Ref10
and MD10, I would also suspect, is still very competitive today, even though the
20i supposedly surpassed it....Ken Kessler felt that was the case when he re-
viewed the latter.
Chadeffect, your fond memories of the Levinson top-of-the-line combo indicates to me that you might be surprised at hearing them today and finding
them to be different from the CD7, but still very competitive. When a component is truly musical and enjoyable, it remains so, even when something else comes along and "betters'' it in some areas. Sometimes in our
pursuit of better, we make lateral moves and wind up going circular and discover a previously discarded piece remains on the same performance level
but just has a different set of pluses and minuses.
When I spoke to Leonard, he did say that this mod was a sonic improvement. I will also be interested to in hearing how so. I suspect the CD7 with the 5881 will run hotter. Though, actually I wish ARC went with a 6550 for regulation. The CD8, and newer Ref3's use a 6550 for regulation. I think I have to wait a few more days for delivery.
