Tomek, I would say that the Panny (either 25 or 50) is likely the easiest to buy in Canada - I have seen several at Future Shop, whereas the JVC and Teac both require cross border shopping, and with the current border hold ups, that can dramatically increase lead time.
Now, as for what sounds best, or what would be best for your application, that is harder. I have not heard the JVC yet, I have lent it to JLM in Michigan. I have only heard the Panny at Future Shop, through some HK surround system - the salesperson was very impressed with how loud it would go... As for the Teac, well I am likely biased there - I own two, and have invested $$ to have Wayne mod one.
That all said, my speakers are FAR less efficient than yours, so it is difficult to translate my experiences to yours.
If I were you, and you are concerned about what you end up with, I would borrow my stock Teac, to get an ear on it for free. If that does not go well enough for you, you can then buy the Panny at the Future Shop to get an ear on that.
If, after hearing both, you are still not interested, then I would think that you don't like the sound of digital, or it simply has no synergistic match in your system.
Sound fair?
