Is low cost DAC worth it?

OP,

Pretty soon you are going to hook up a decent streamer and DAC and hear why they are important. However if you don’t invest some money in both it will sound like a waste of money. So far you have been splashing around in the kiddy pool.

Soix, i've been on a similar journey and had similar results as you. I'm currently way beyond the streaming and DAC components I mentioned earlier.  I was only trying to relate an experience I had that could improve upon the OP's current situation and at the same time keep things within his stated (very low) budget.  No question a good steamer will improve the listening experience.  The two Aurender streamers that I currently use, one in my speaker system and another in my headphone system are huge improvements from experimenting with a phone and other lesser streamers that i used before Aurender. Again i was only trying to suggest another method that had been suggested to me by a well respected person in the industry that worked rather well for me using something people already have, a cell phone.  I understand that your experience was different using a phone.

And after re-reading what I said above, i could have been clearer in my point.

Folks... I really, really appreciate the discussion.

One of the things I am wrestling with is I'm not as young as most of you an my hearing is not great, so at what point is spending money a waste.  

I love the journey you folks are willing to help me with.

And this may be my favorite response......
