you could check out Audacious(1). its the GTK2 successor to XMMS, retaining its plugin format and native ALSA/JACK output (the other main fork of xmms, BMPx, now uses GStreamer). 

im a bit concerned that you claim the quality is less. i know some windows players (namely foobar2000) boast of full range 32bit-float interpolated decoding of originally 16bit sources. generally theres a choice of mp3 decoders: lame,mpg123,mad. youd have to experiment with compile-time options and different apps to see which one you prefer. the only other likely source for quality loss is a realtime resampler from eg 44.1 to 48khz. many mediocre soundcards, particular with jack, tend to default to 48khz, or are even unable of operating at 44.1 directly..

FLACs sound fine to me in audacious. even with ATIIXP onboard sound piped to a set of unpowered(!) monitors directly from the headphone jack...
