well she did complain about mp3
player quality, so does not appear to understand
digital audio. its all 0's and 1's until you get to the D/A stage, and all the MP3 player does is send those unaltered 0s and 1's to the sound card or chip
shes probably one of those folks who think that dropping $99 or more on a gold-plated oxygen-free HDMI cable gives you a better picture, ( just like how a $999 printer cable improves your print quality) ....we're drifting way off topic but given a lump sum to spend I'd go for a mere 1000 - 2000 recordings ( that's a hour a day's worth for 5 years

), and spend the rest on a world class sound system , not 5000 records ripped to MP3 for PC playback - but each to his/her own.
Even with an expensive soundcard, my Dell PC motherboards add a certain amount of noise to the audio channel , which no amount of cable/component swapping will cure. it's not an issue at normal in-house listening levels but if I crank my 100w amps to max, with no track playing there's a LOT of noise, compare with what I hear after unplugging the pC audio & connecting a dedicated CD player.
Its not earth loops or anything like that, it's that mass market PC motherboards are not built to audiophile tolerances. audio/video crosstalk is the primary cause but general E/M radiation from unshielded PC components will always affect analogue audio out.
Digital out from PC & hi-fi amps with digital in could be better but are out of my price range. - they are anyway aimed at multi-channel Home Cinema crowd. If you look at upmarket 2 channel stereo HI-fi amplification (to match what is on your vinyl / your Cds ), its all analogue stuff.
But hey, if you are collecting great classical recordings by the 1000s, you probably have stuff remastered from old 78s / recorded with a bent pin on a lump of wax so what the hell . Anything pre 1980s will be analogue mastered, on tape ( remember tape???) , then pressed to vinyl. Caruso did not release many DVDs
PS The idea of "alleviating.. losses in compressed formats" is a marketing hype thing. you can't really interpolate & replace what was removed during compression, despite Creative attempts to make you think otherwise.
To drag it back to a book discussion , it's like selling software that can restore your
abridged book to it's former
unabridged glory.
