Used Rowland 302 or H2O Signatures CD Direct


I am looking for an amp to run a pair of Magnepan 20.1 speakers. I have heard great things about the H2O Signature Amps. My main concern is I have no preamp and don't plan on using one. I am using an Audio Aero CD Player directly. So the question is does the H2O amp require an active preamp? If so then would I be better served grabbing a used Rowland 302? Also I have read that the H2O requires a shielded Power cord. Does the unit come with one or would I have to buy one?

Thanks for your help...

Muralman1- Hopefully Henry will still be in business a year from now and your amps will still be functioning.

I nevered owned an Magnavox console, but I sure my mom leaves me her RCA stereo console. ;-)

PS- Supra LoRad is a better sounding shield power cable than the DIY Belden. DS has one.
There is no reason Henry won't be in business for many years to come. He is doing what he loves to do.

I know DS has a LoRad. I think the Belden will sound better. :)
According to Rowland,the switch mode ps converts to pure DC.Would this eliminate the need for something like a PS Audio Ultimate outlet or any line conditioning/regenerating devices,in an apartment house setting?Thanks.
The GCC-series of class-D amps by PS Audio have 5 inputs, and other intuitive convenience features that most other amps lack. I don't know how they compare to the H2O's or the Rowlands, but they sound very good in their own right. You may want to check them out.
