Question for you analog High Fidelity experts.
My smart tv has an audio outlet which I have connected to an analog converter and then into a Bose Wave Radio using the Aux circuit. This is great improvement in sound quality. The problem seems to be that the converted signal into the Bose radio must be weak as the amplification is not much even with the radio volume up high. SO, I am wondering if a pre-amp between the analog converter and the Bose radio might be effective in increasing volume? If so, can any analog amp be used?
Any thoughts?

First, try higher volume on the TV with you current setup to see if that helps. If not, check to see if the TV sound output setting is set to fixed or variable. Variable output varies the output with TVs vol and you may be able to up the TV vol for a stronger/better output signal to the Bose. If not, your best bet without spending more on a pre-amp (which may over-drive the Bose to distortion) is to follow Bose instructions to use the RCA analog output from the TV if it has them. Connect RCA to 3.5, to Bose aux, set the TV sound setting to "fixed" output, turn off the internal speaker and set the TV volume to 80% of max (according to Bose). I would try variable output as well, as fixed output is not varied by the TV volume - not sure why Bose says to set to fixed AND set TV vol to 80%...

The digital optical output of the TV is fixed. On this set, there is no output volume setting since the signal is not analog. If I read your comment correctly, a pre-amp could be used to boost the volume from the Bose Radio's speakers. Just do it carefully so as to note over load them.

I am guessing that the Digital Optical to Analog Converter produces a "Line Level" signal such that a pre-amp is not likely to help here. Not an expert on analog audio, so that is a guess.

It would probably work great going into an amplifier instead of a radio. A preamp would be worth a try.

You can get a mini amp and really good little speakers from Parts Express for $60 to $80 that would make it sound great.
