Any other components go with this Technics M7 tape deck?

[Ringside]

Hello all,

I recently picked up this tape deck for $10 when I had the urge to listen to a few of the old tapes I'd held on to.

Anyway I'm wondering if there's any other matching components that go with this deck?

Here's a link: http://www.radiomuseum.org/r/technics_stereo_cassette_deck_rs_m_52.html

Thanks all!
