If possible to take the price out of the equation for a moment, I suspect you’ll find you can get more than 80% results by simply comparing preamps and selecting the one you like best. And if that comparison is blind, I’d guess the odds of your grail being affordable is quite good.
Many who equate SQ to price will disagree with me but I find that in high end audio, you often do not get what you paid for. You may get polished aluminum faceplates and heavy remote controls, but with your eyes closed, the reality is much different.
choose wisely and remember, you do not need to blow your child’s college education to achieve a stunning music system.
