OLD POST l KNOW but still relevant for someone in the same position. New Cambridge CXC CD player (or a second hand 752BD Universal player)
Find a Cambridge CXC transport and you will have an upgrade but will need a DAC or compatible amplifier. I have both a CXC and a Cambridge Audio 752BD (SACD/CD/DVD/Blu-ray) which l will keep for some time to come. Both would do the job of an old 740. The 752BD is a very capable CD player, has onboard DAC and the upscaling TV 4K is a plus for a Blu-ray player.
