The DBLs are definitely not one of the best TTs every made… But they’re definitely one of the very best speakers
A lot will depend on the set-up of all components in what should be a wonderful system. What cartridge are you using, Gab? Also, when where the amps last serviced?
The CDX2 can be bright and piano notes can ring unnaturally. Put it on a steel framed rack and let the cables touch it and maybe a hard floor and that’s what you get. Put it on wood or best full Fraim and let the cables hang free and it’s a much more pleasant proposition. A good turntable might still show it up a bit though.
It could be an idea to try before an « old » Naim CD player such as CDS or CDS2.
In my opinion, a single player is not at his best in such a big system!
Source FIRST…
A TMS3 in good condition with a decent arm and moving coil cartridge is one of the very best sources you could ever use. It can far exceed the capability of a Naim CDS3/555PS and I say this as a former owner of that very Naim CD player.
