I thowing in my vote for the Sharp EX-111 for $75. I love it because it sounds great, is compact, has a built-in CD player and tuner, and is convenient as hell. Very cool and good sounding all-in-one unit with remote. Inexpensive, too.
Unless your GF's mom is a gearhead, I think she would be happy with this and good pair of speakers.
I also have a JVC ES1sl. This unit is very nice, but unless she has room for a full-size component footprint, the Sharp will fit into a non-gearhead's lifestyle better.
Just so you have some perspective, I have five tube amps including Audio Note and Sun Audio 300B amps, have owned a Moth 2A3, Chord solid state stuff, 47 Labs Gaincard, Cary, Sonic Impact, etc. etc. plus worked at a "high-end" store, and I strongly recommend the Sharp for anyone who wants good sound, convenience, compactness, and simplicity. I own two of them and have recommended them to my brothers and a couple of friends who are not into the audio hobby.
I don't think you can beat it for the kind of system you're setting up.
Good luck,
KT
