Wyred 4 Sound Class D Mono blocks SX 1000 question

Does B&O have newer Icepower modules, sure they do but if you think your amps still sound good then that is all that matters.  EJ has had the new 1200as modules in-house for testing them for a while so it is only a matter of time before he decides to use them in amps at "reasonable" prices.  The other "name brand"  company's amps using the 1200 modules at this time are all priced much higher than what W4S amps are likely to cost.  The alternative to waiting for them is to buy from one of the European direct sale companies like Nord.  

Horribly obsolete, you should send them to me to use with obsolete 1990s Adcom GFP-750 and Magnepan 3.5s.  

Seriously, just as with many things, incremental improvements.  

if they sound good they are good

I owned a pair of the SX 1000 mono-blocks and they are good amps, with that said remember there is always going to be something that has more dynamics and sounds better. If you like what you hear relax and enjoy the music.

i have 70s amps don't seem to be obsolete at all.
