I only mentioned the phono stage because the reviewer pointed out the A90 sounded 'warmer' through the Slee.
Myles...
All I am saying is that to hear how good the A90 is, is it not worth putting it with the 'type' of equipment it will be used with? I don't know about you but I heard that the Cambridge audio 640p was a good phono stage...I heard one in my system and it sounded CRAP! Compared to what I was using at the time, the Cambridge sounded.... well crap!
Some folks think the 640p is as good as if not better than the Slee units. I have found that after the TT/ Arm/cartridge combination the phono stage is a definite next big stage. I like many here have found that they can either 'hide' the cartridges capabilities or bring them out.
Things like RIAA accuracy which the mags 'bang on about' is irrelevent, because most stages are pretty much the same when it comes to RIAA specs. Like any amplifier, it's how the cartridge signal is 'processed' that makes the difference.
I think it was wrong to play the A90 though a cheap phono stage and 'hope' to really hear what it is like. The Slee like many other cheap units don't image that well, have a very limited sound stage and don't sound as 'real' as the higher-end products. So, playing an A90 through that will give you the wrong idea.
