The longer I think about this (interesting) subject, the more difficult I find it to name any current or recent amplifier that will go down as a classic.
In a way Vladimir, though endearingly naive but enthusiastic at times
, is correct in that a product in this category is probably best just an amplifier without any add-ons such as streaming etc. which will probably be superseded by something better before the blink of an eye. - I'll take my devialet recommendation out of the equation for that reason, as good an amplifier it probably is and as technically interesting it comes over at with its unique power-supply and speaker matching software. Their current range will probably seem old hat in a few years.
It is also for this reason that I cannot nominate Sony's absolutely stonkingly superb STR DB930 (which I have). I cannot think of any way of getting more amplifier, good phono stage and DAC's for the money. That it has been compared with superlatively expensive Conrad Johnson amplification only helps its matters but as the Devialet, it is a product that has certain things which have now been superseded and make it read dated (S-Video anyone?) - Grab a mint one while you still can would be my advise.
That probably just leaves simple amplifiers which will even in a few years time have their loyal following because they do the one simple thing they do, well.
So, as much as it pains me because of the current hype surrounding this relatively common and simple amplifier (I should be used to it by now, this is hifi after all) , I guess, the Brio-R could be there somewhere as it is relatively affordable (but not a bargain imo) and will be so increasingly as years go by.
As, I imagine, could be something like Marantzes 6004/5 amplfiers, for the same reason and being even cheaper and accessible to many a student on hard times. Plus it will have sold probably many times more than the Brio-R.
But and I am obviously biased here, for relative affordability in the greater scheme of things plus it's iconic looks, engineering prowess and upgradability in form of a 'relatively' (!) cheap power supply compared to some others I nominate the Cyrus 8vs2 as a future classic. The model before they tried to pack to much into the lovely, slender skandinavian made casing.
There you go
