Just bougth a "Philips" 32'' TV which has one SCART, and I think a lot of others have that, too. So you can connect the "best" source to that w/o losing quality from an adapter.
Generally the rule of thumb is to use the adapter at the "end" of the higher quality, e.g. if the source has HDMI dont change until just before the lesser-than-HDMI (e.g. hdmi-to-smart just at the TV).
IoW, since your sources are all on the "low" side, you wont lose much (if at all) by adaptering it to HDMI.
