CD Player: Vintage or modern ones?

I have 2 systems, and have an Audiolab 9000CDT on both. Great transfer unit.

PS: what is the benefit nowadays using CD’s instead of a nice DAC/Streamer combo?

Both good/great is done right BUT the selection with streaming is astounding. Go to a show or shop and check it out. Lot's of good used stuff for starter streamers or higher end steamers always around.  

The "benefit" of CDs is that you don't need the internet and a cleaned up ethernet chain. Less parts are needed too.

Sonically, with both done right, there's scant difference if any. High end flac files (steamed) are tops.

My CD's are in a closet and CD player is too. Both are kept in case the internet blacks out for days.

It depends on the quality of the CD player. The old Naim CDi that I inherited from my late Dad (RIP Dad 💔) is built like a tank and still sounds great over 30 years after it was manufactured. Of course the CDi would cost over $9000 today factoring in for inflation, but nice ones can be found from time to time for around a $1000US. As is the case with all vintage audio gear, finding parts can be an issue though. So caveat emptor. 👍

Unfortunately old lasers burn out sooner or later, and are often irreplaceable.  I'd be looking for an inexpensive transport (even a universal player including SuperAudio CD playback) and spend the leftover loot on a good DAC,  I do not know of a streaming service that outperforms multi-channel SACD ...

Have you tired Qobuz larger FLAC files on a higher end streamer and DAC setup? It's not possible to hear any difference.  My test subject is just me.
