The mention of rolled off frequencies with the VK-500 is actually quite attractive to me considering my very bright B&W dome tweeters (CDM 9 NT) and my choice of recording material (indie/underground). At the risk of sounding "shallow", my only problem with the VK-500 is it's appearence. There are similar highly regarded amps such as the MC402 and X-250 which are quite appealing in both look and sound. However, the more I read about the VK-500, the more it seems like the perfect sonic fit for my system. However, I am still open to other options and would love to hear from some VK-250 owners.
