difficulty finding CD player match for Magneplanar

I used to have an Icon player and the MG IIIa's also.

I replaced it with the Denon player I use now and I thought that an improvement.

The mhdt Constantine DAC I use with the Denon currently in my system is the best combo that I have had yet.

You need considerable power I believe to get the best out of those Maggies, I believe though.

My Muse model nine CD player has superb bass, it really has that quality that makes me want to listen again and again. Another classic is a Meridian 508/24, very engaging.

fwiw both these players are a bit old but stand up very well.

I don't want to insult you, please understand, but ditch the adcom preamp! I would start 'home trying' lots of other pre's or, try a really good passive pre with the cd player and your reaction should be WOW where have you been all my life? yeah the other guys are right about the maggies needing some power and current... 150 - 200 watts per channel and some current dumping ability.. THEN try out the Saturn!
I have a Rega Jupiter 2000 I am VERY satisfied with.. have tried it with various speakers and the whole sys. ROCKS with my vintage modded JBL Horizons...
BTW the Maggies are excellent! Keepers-- hang on to those.

Before dumping money into other things, let's start with your original question, were you happy with the sound you were getting from your CAL player, in your system?

Timoteo, like most previous answer suggest, you have a very serious bottleneck in your amplifier. I have used your very Maggies 3As for 20 years. . . All Magnepan speakers are major serious power hogs! Not even my original Aragon 4004 was making them happy at 200W per channel. They became a lot happier with the Rowland 7M monoblocks. . . plenty of power there. . . very effortless but not yet enough control for the bass region as their damping factor is only 175 or so. Besides, the old Rowland 7M run very hot to the touch and were simply not right for Texas summers. Your Maggies will truly shine if you feed them what they crave to recieve, lots of power and a relatively high damping factor of perhaps 250 or higher.

You may want to look at amps that are between 300 and 500 watts per channel. Such amps can be real drags on your monthly energy bills. . . unless you use amps that run cool to the touch: some class A/B amps with low bias, and most class D amps would fit the power requirement.
In pure amps I warmly recommend the Bel canto Reference 1000 Mk.2 monoblocks at 500W per channel over 8 Ohms and 1000W over 4 Ohms (the maggie's impedance) and a damping factor of 1000. . . don't be deceived by their small size. . . their sound's deliciously amazing and they even handle my current Vienna Mahler speakers, which may be even more difficult to drive than the Maggies 3As.

If you were willing to consider an integrated amp, you may look the Rowland Continuum 500. . . same 1000W per channel over 4 Ohms and 1000 damping factor, with 40 Amps current of the Bel cantos, with probably a more sophisticated AC power rectification front end and more bulk capacitance in the output, combined with a killer linestage circuit. . . same found in the Rowland Capri pre.
If cool operation were a major factor for you, the Bel Cantos run cooler than the Rowland. . . the front end PFC-based AC rectifier in the Rowland Continuum 500 generates a fair amount of heat.
Only thing to watch out is that class D amps take several hundreds of hours of break in to sound at their best, otherwise they can sound EXTREMELY dry.
As the amp is definitely your weakest link by far, initially you may want to consider getting a relatively inexpensive CDp, such as an OPPO, which are reputed to be fabulous price performers. . . then invest in a higher quality CDp later on if you were not yet satisfied of the results.
