Hi. I bought the Unlimited after listening to their little brother which I bought in the local Craigslist. The Unlimited is an excellent preamplifier. In my system it replaced a EE Minimax. I agree with Kalali 100%, I think he nailed his assessment of the Unlimited. In addition, Aric is a great guy to work with. In my case he added an extra set of input jacks for a modest price. I've owned a series of high end preamps and sound wise the Unlimited beat them all. One thing I noticed is that the new Unlimited only has two 12ax7 while mine has three. I'm not sure why that is but i'm very happy with my purchase. It would cost two to three times what I paid to get better sound. This is a highly recommended piece of equipment if you are in a budget.
Aric Audio Systems Unlimited Preamp
They have a tube model called Unlimited that appears to be a decent value for < $800. It is tube rectified and with pair of tube voltage regulators and 12AX7 driver tubes. It even has a phono stage. Anyone is familiar with this preamp?
