If you are having occasional problems with clipping, getting another integrated amp with marginally more horsepower isn't likely to solve your problem. Remember that to get only 3db more gain (usually regarded as about the lowest audibly noticeable increase in volume), you need to DOUBLE the power output of the amp. Put more directly, if you want a LOT more listening volume, and to avoid clipping, you may need 6-9 db more gain, or 4-8 times the amount of amplifier power you currently have. Hence, you'll need to get an integrated with at least 150 wpc to realize even a minimal increase in volume/gain. If power is the issue, there are two ways to solve the problem: get more efficient speakers (such as those made by Coincident Technology), or get a more powerful separate amp. If you decide to pursue a more powerful amp, then you may want to get something in the 200-250 wpc range, and use your current integrated amp as the preamp. Or, for your $3k budget, you could get something like the Bryston 4B-ST power amp (rated at 250 wpc, but actually closer to 300 wpc), which sells new for $2400 (I know a dealer that sells the 4B-ST for about $1750, if you are interested) -- or you could buy a used unit for around $1500-1600, which would also leave you enough money to get a good used preamp -- such as a used Bryston BP-25. Before you decide on what to do, you should give some thought to your overall objectives for your system -- if power is your primary issue, you may need to upgrade from your Sim Audio integrated amp (which, by the way, is a fine unit, which may suggest that new speakers would be the way to go if you like to listen at higher volumes).
