Is there any "volume attenuater"

Hi,I am interested to get the Stratos amp(Odessey) with the thought of hooking it up DIRECTLY to my AhTjoeb4000 CDP
(using its remote for Volume Control).Just to get a "flavor"
of what it would sound by this kind of a direct connection,I used my NADC370 Intergrated amp for experementation(disconnect the u shape jumper of the amp and have the IC. connected between the Main-In socket to the CDP). The sound is so full and LOUD even when I set the
voulme on the remote to MINIMUM. I wonder if there is anyway
I can get a divice(a "volume attenuater" so to speak,if my description is correct)that can be "connected" or "hooked up" to either the amp-side or the CDP-side.Then I cab have a "late-night musical enjoyment".This idea came about just because I bought my NAD amp a few month only and I don"nt
want to spend on getting another Preamp. Just thought of consulting you guys, your opinion suggestion is highly appreciated and thanks alot.
