Yes Michael, your Lector you should have kept, as it had the best R2R chips, 2 x PM1704-K "K" being selected and a cheap easy to get SF-HD65 laser.
These PCM1704 and the 1702 were the best and last of the R2R Multibit dacs chips made. Now they’re all discrete R2R Multibit some better some worse.
My Linn CD-12 had 4 of the PCM1704K’s in it with a great sound, full bodied yet tight and very dynamic, great boogie factor.
Your on a budget, to get back into that sound cheaply try to hunt down a Cary CD-303-200 it has the PCM1704’s and the very good PMD200 HDCD filter chip and uses the VAM1202 laser still obtainable nice and cheap should you ever need one. https://www.stereophile.com/cdplayers/504cary/index.html
Or even a California Audio Labs CL-15 https://www.stereophile.com/cdplayers/1198cal/index.html but the laser RAE0113Z is also getting real hard to get.
That Denon yes uses the PCM1704 but the lower PMD100 HDCD filter chip, and it’s laser VED0378 is getting well over $100 and hard to get.
I now have a MSB discrete R2R and love it.
R2R conversion done right just has a real live rich sound, unbelievable on good recording. But it "can" give you warts and all on the real bad ones.
Where DS (delta sigma) to me is smooth and is better for bad recordings, but at the sacrifice of being just a bit of a yawn on the good ones, but it does DSD and SACD that’s what it’s good for.
Cheers George
