Yeah if you can find a good quality vintage turntable then maybe it's not as expensive . Not sure why you feel that you have to spend 700 Euro for a CD player . I feel the CD is too limited to justify such a high priced player . Besides if you connect the CD player digitally the DAC of the receiver/amp will matter more than the CD player .

Actually you needn't. Basically, 16 bit and 44.1 and 48 kHz PCM capability can nowadays be considered as a legacy function of modern DAC chips, which most usually are nth order "single-bit" delta-sigma DACs, which need comparatively high internal clock rates to perform well at higher resolutions, as delivered on some higher resolving physical media or via streaming, and for which (possibly in combination with suitable receiver chips) it is an easy job to asynchronously upsample lower input resolutions in good quality.

Or in other words: Due to the need for higher quality in the studio, for home theater purposes as well as SACD and DVD-A, first 24/96 PCM, then 24/192 PCM and 1x DSD/PDM and nowadays even higher resolution capable DAC, ADC and CODEC chips (as well as matiching receiver/transmitter/transceiver chips) became cheaper and dominant on the market, especially for lower operation voltages as desired for mobile devices but also generally for cost and energy saving. And with these high-res capable chips you can regard it as somewhat arbritry, at which stage a lower resolution input data format is converted to whatever may be the actual internal operation format of the chip, so that you could compare that to using library function of a computer programming language, in which case you basically just need to know its purpose as well as its input and output format, but you don't really care, how it actually processes the input data into the output data.

What I mean is that CD players with higher res DACs can't conjure up something that isn't on the CD so you can't expect them to sound as good as native higher res sources .

CD is in decline and to justify the costs of production of unpopular format, they need to repack it in something that sounds "better" and "high-quality". It is a market strategy. CD has too much limitations to be a serious audiophile format.
"Better" and "high quality" CDs were made even back during the format's heydays. XRCD and MoFi 24K gold CDs have been around for decades.
