Very good connection options

Output RCA or 3.5 mm jack

Power cable for USB can also be connected by means of a small power plug to 230V power outlet. Short cord !!!

Therefore optimum connection possibilities.

Gold plated contacts

Processing makes good impression

Sound compared with CD player from 1991 then 250 Reichsmark (The CD player has Coax output, hence direct test of the DA-wall possible):
CD player and DA converters in approximately equal volume with the DA converter minimal (but insignificant) is quieter.

The CD player sounds fuller, more massive, more volume, but also sharper (within the meaning of unpleasant) and imprecise. Here deliver an accurate picture is difficult because I have some years carried out no hearing test.

So connected DAT reference instrument from 1991. Run reference recordings of Susan Vega. Of course, with the best finger-thick and selbsthergestelltem RCA cable.
Test listening difficult because not exactly the same volume. Only minimal difference, but which is crucial to the ordinary test hearing.
After prolonged testing hearing the same songs over and over again the difference is then always more audible (in other words, a layman not rehearsed it will probably be able at short test listening hardly notice):
The DAT plays free out, up and down. Is more present (and not just because of the slightly higher volume).

But: The DAT has played loose against the wall of his time even CD players of 3500 Reichsmark.

Therefore, this converter is certainly worth the money. Even if the unit does not sound comes to a DAT reference instrument from 1991. The other thing is that you must then also have corresponding reference photographs to here can ever make a judgment.
Who needs the device for the already not particularly great sound of a TV, but it's almost too good ;-)
Even with various MP3 recordings you will surely be able to notice any appreciable difference in sound more here.

Who does not belong to the high-senders and not (no longer) has the best ears, which should completely pass this part.

I myself was at that time even get to hear the sound of various RCA cable. Not advised! But marked and changed by another person. Hit rate 100%! Whether I still can today, I do not know. I think I would only times for days practice test listening, if not weeks.

Conclusion: Since most buyers buy this device for connecting TV to stereo and not because they want to improve older devices sound, full 5 stars.
Anyone who wants to improve his old unit, which should make absolutely sure that you buy it there, where you can return it after testing, as surely as my cheap old model here certainly can compete even newer CD player also. Hardly suited to bolstering the sound of hi-fi components in my opinion. As it stands at fangled MP3 players, game consoles, etc., that I do not know.

Device depends now on the optical output of my Samsung TV. The volume knob I have to turn up here considerably higher than the DAT or CD. I assume that the television signal is simply quieter. It's yet another reviewer here said that is noticed. Regardless, there is this volume control, with which you can adjust the volume ;-) sound great! No difficulties.

I hope I could help.
