I think Jackdaw was (correctly) pointing out that there are losses involved using any of those methods, when compared to direct consumption of power. At every conversion, something is lost, so the fewer conversions, the better the efficiency.
Stereo/CD players--new technology; what's good?

We may not be using the term "losses" the same way. There are losses when converting solar, or wind, or hydrodynamic, or shore power energy to the volts stored in your house bank. There are further losses when recharging battery powered devices on your boat from the house bank. The progression from each of those states to the next is not 100 percent efficient. Each component - connectors, wires, switches, chargers (big or little, hardwired or plugin), diodes, whatever - takes its little share. It all adds up. Only superconductors have no resistance to current flow.
Think about just one example: we size wire to mitigate voltage drop in longer runs. What is voltage drop if not a loss?

If your old radio has an AUX audio input jack you can add a very nice Bluetooth receiver for under $35. You will also need to power it from a micro USB cord (same as you use to charge your other USB powered devices) although it has an internal battery that will last quite a while. This is the one I use https://www.amazon.com/gp/product/B01K8ANDCI It works great.
...If only we didn't have RESISTANCE, then we would need no batteries.

BTW different batteries have different internal resistances and thus different charging energy..
Exactly. Yet another net loss.Only because someone used energy to make Liquid Nitrogen or refrigeration.
Charging a 12v device battery from your 12v house is maybe 90% efficient. So you lose 10% right there. So its better if you just have a device that uses the 12v house. If it can wait to charge an external 12v battery powered device until you get back to external (120v) power being available, then you could have been out that long at all. That's not cruising, that's day sailing.
Just brought my IP into the 21st century.
Next, install new speakers in the cockpit. PO hard-wired speaker connections in the laz, so it doesn't make much sense to go BT there.

This BT device that does that.

You could split the analog audio BEFORE two older BT transmitters and pair 1:1.
When we fly Jodi and I used Bose QC35 BT headphones that allow sharing of a single source, as long as the source broadcasting from an iOS device. Fun to listen to the same music or watch the same movie.

I "settled" for the Sony MEX-M100BT (Bluetooth Audio System); so, I feel I'm now maybe half-way into 21st century technology for boat systems!! (The Bavaria is a 1999 model year.) It was not a fun installationHi,
Thanks to everyone for your great suggestions and testimonials for a new/up-graded stereo system for the boat. I'm looking forward to installing something within a week or two. I'll report back when it's in

. As it turned out, and I can't believe it even now; but, evidently, both cockpit speakers had failed at effectively the same time with the old Kenmore in place. I could have just put in two new speakers, which I had to do anyway, but only after all of the "fun" I had installing a new harness and power leads for the Sony. Conferring with Sony tech support was unproductive as well as very frustrating; but there was other frustration. A big one being that "boater's store" with the initials WM 300 m from where the boat is now slipped. The Sony instruction manual helped only after I'd figured out everything I needed to know that was not in there!! Now, the admirable and I are looking forward to enjoying the new sound!

I just installed a Sony DSXM55BT (& two Bose 161s) without trouble (after I cleared the air from the sparks and smoke caused by two old wires with poor insulation getting too friendly ).
I broke down and did it after getting tired of looking at the PO's cassette player.

Glad you found a solution that works for you.
For anyone else still looking, I went with one of the Fusion radios mentioned by Jackdaw and others. One of my favorite features of this radio is how easy the fader is to use. On regular car stereos, it's often hidden in an audio settings menu. On the Fusion, a quick press of the volume knob and it shows "Cockpit" and "Cabin," easily switching volumes between the two.
We also use the N2k feature to control volume, tracks skipping, etc via the chartplotter at the helm.

I went with the Sony because it fit the hole. I also don’t have cockpit speakers.
