Just bought an Arcam A38...
I have probably been my own biggest fan of the A28 I had until a few hours ago. I have been using it as a poweramp of sorts, utilising my Leema dac as a pre.
So I saw the A38 at a decent price and the very friendly seller took my A28 in part ex for a nearly new A38 and the deal was done!
First impressions are very good; generous and well controlled bass, superb soundstage with far superior organisation and very detailed midrange. In fact, vocals and instruments sound far more realistic with guitars and drums in particular sounding far more natural, allied to a more powerful presentation.
Now I have to caveat this by letting you know I did not complete a triple blind, ABX, upside down test and there were no scientists present to record or analyse the results, so my findings are probably utter b*ll*cks!
