I sold my passive preamp, I searched high and low for a good preamp to replace it. The choice could have gone for an old used glory, but too risky; I like the devices of the past, but the risk of finding myself with some problems is always around the corner. I thought about it for a long time and in the end I took Pre90. It has enviable measurements, I don't need any more inputs, by all accounts it is almost unbeatable, it has an enviable price-performance ratio. What can I say other than confirming all the praise for this product. It works excellently, and frankly I think I would never have achieved the same result with an old and noble preamp. Indeed, I would have risked yet another heirloom hanging in the room...
