Big Difference With New Source?

I must respectfully disagree with some of these posts. I am not a Linn fan but I agree with his philosophy in regard to hiarchy of importance. The single most important thing you own is your source, LP, CD, or whatever you use. The second most important thing in your system is the piece of equipment which retrieves the music from the source. I don't care how good your amp or speakers are, they won't add what your CD player didn't get.
Get the most off of the CD or LP by investing the better portion of your budget there and then work back to the speakers in decending order of priority.
I just bought a Sony SCD-777es and am really impressed with the sound of redbook CD and SACDs.
Shop smart!

I also own the NAD 541 and recently upgraded to the Rega Planet 2k. The differences are not subtle. I brought it home from the dealer for an audition thinking that I'd get my gf to help me switch between the two units without me knowing which one was playing, but after about 10 seconds of hearing the Planet, I knew that an A/B test wouldn't even be necessary. Quite honestly, the Planet blows away the 541. The soundstage is wider and fuller, with more presence to the voices and instruments. The 541 sort of sounded to me like there was a hole in the middle of the soundstage... the Planet is very solid from left to right with better width, depth, and height in the soundstage than the 541. Imaging is better too. It's easier to tell precisely where an instrument is coming from, and there seems to be more space around the instruments. You also get a little better detail than the 541. But all of these improvements pale in comparison to the improvement that the Planet gives in pace, rhythm, and timing. This is a quality that's hard for me to describe but its something that the Rega excels at. With the NAD, it seems like the presentation is a bit cold and analytical, while the Planet seems very lively and just makes me want to smile and tap my foot to the music. This is a very intangible quality, but one that I could detect from the very first listen. The Rega also has a warmer tonal balance, which can be a plus if your speakers have a forward treble, as mine do.

Some people are going to say that digital source doesn't matter or that all cdp's sound the same. I can only say that to my ears, the Planet 2k is a night and day improvement over the 541. If your budget goes up to $2k, you might also want to check out the Jupiter, which I haven't heard but supposedly its even better than the Planet. I upgraded my speakers before the cdp(I went from JMlab Chorus 715 to JMlab Cobalt 816) and as much of a difference as the speakers made, I think that the cdp made an even bigger difference. The 541 is a decent cdp for the money, but even for $1k you can do a heck of a lot better. All IMHO.

My experience with digital front ends is probably similar to a few others out there.

I had started off with a cheap CD player many, many moons ago. Over the years, i had changed players. Sometimes out of wanting something new, sometimes out of having to replace a player that was "wounded". There were some subtle changes along the way, but nothing really major. Out of all honesty, i think that most of the improvements were simply due to the normal "trickle down effect" as digital technology has grown over the years.

All of that changed when i picked up a tubed DAC. While i had tried a few different SS DAC's before, i was not prepared for the difference in liquidity, increase in soundstage depth and air, separation of instruments, drastically increased "musicality" and overall improvement that came with the addition of the "antique" technologies known as tubes to the digital signal. It was by far the biggest step forward in digital that i had ever taken. There was no more digital glare or "sterility" that i had so often encountered in most digital recordings and presentations. Instead, there was music that flowed freely from my speakers like never before from a digital source.

I was overjoyed to say the least. I liked it so much i ended up buying three more tube based DAC's ( some 18 bit, some 24 bit ) for other systems. Along with that went the associated variations in tubes, etc... It was both fun and enlightening to see the differences that various makes of tubes could introduce into a system. I was in "digital bliss", or so i thought. Little did i know that this wasn't going to last as long as i would have thought.

One day a package showed up at my shop. It was a DAC that i had ordered months and months prior. While it was an SS unit, i was guaranteed that it would put my tubed DAC's to shame. I was told that i would have the speed, frequency extension and transparency of SS with the warmth, liquidity and natural presentation that tubes offered. If i didn't experience this, i was free to return the unit with no questions asked. Needless to say, i was both reluctant and excited at the same time.

Upon hooking the new SS DAC up, i was immediately aware of how precise and clean this unit sounded. Not only did notes pour forth with razor like precision, they did so as effortlessly as Nolan Ryan threw a fastball. The sound was pure yet had such a soft and liquid character with great extension at both ends. I new my "old flame" of a tubed DAC would seem like yesterday's news. That is, if i were to ever hook it back up. I did do that, but not for quite some time. The difference was so startling and instantaneous that it swept across me like a revelation sent from above.

The bottom line to all of this was that i had reached a plateau at one point. This took place after literally trying over a dozen different players, dac's, etc... from various manufacturers. I thought that i had reached a point that would be hard to surpass. Then, all of a sudden, something rose above that plateau to show me that there was the potential for better performance and increased enjoyment. Just as i had come to rest on what i thought was a pleasant plateau with my new-found love, another product awoke me from my slumber on that plateau to push me forward. While i have moved forward from that "push", i am now pretty content with what i currently have. That probably means that there is something coming my way shortly that will make me sit up and take notice. That is, IF i want to.

I'm sure that there are others out there with similar stories and experiences. As such, their system and yours will only evolve to the point that you want or will allow it to. Sometimes the step forward is very noticeable and quite large. Sometimes it is gradual and made up of a bunch of smaller steps. Either way, there is always new ground to be explored with most of it being at least "different" if not pleasurable. It all adds up to what most would consider to be an educational experience in what can be a very fun and enjoyable journey.

Do your homework, demo as much gear as possible and spend your money wisely. If you play your cards right, you can check out quite a bit of gear in your house / system without really losing money should you decide to keep rolling things over. Variety is the spice of life and i encourage you to partake of that "spice". Why settle for less when there is so much more out there : ) Sean

so Sean, after all that you didn't even introduce us? What's her name?

With a revealing system, changes in source are very apparent and IMO establish the basis for achieving a natural musical presentation devoid of the digital artifacts that we all seem to dislike. I have an NAD 541 as my cdp in a project studio with SS into Tannoy monitors but I wouldn't use it in my dedicated listening room for classical music (there I use Merlin VSM-Ms with tubes). I have used an Arcam Alpha 8se, CAL Delta / Bel Canto DAC 1, and Dan Wright modified CAL Delta / Tact RCS 2.0 internal DAC. Each of these had its own character (as did the selection of digital cable connecting the transports and DACs). I think the choice of equipment (including cdp) depends upon what music you want to listen to and your personal preferences about sound presentation. My Arcam was more forward and very detailed while the Delta/Bel Canto combination was more laid back and smooth. I preferred the latter but I can imagine others preferring the Arcam. I've never heard the Rega Planet 2k but from everything I've read, my guess is that it would be a great match for your equipment based on what I like. YMMV however.
