Spectral Audio DMC 10 Quality

Hello Everyone!

I'm a newbie here and I've come with a question I hope someone might be able to answer.

I'm in a bit of a situation where I have to explain the quality and cost of the Spectral Audio DMC-10 to someone who isn't familiar with high end audio. This all pertains to insurance coverage. The company likened my equipment to a Pyle Pro Pre-Amp, which is only just over $100 retail. Obviously the 2 are not the same!

But how does one find the retail or replacement cost for high end vintage audio? I don't think eBay listings will do.

If anyone has a suggestion, I would most certainly love to hear it. And if anyone has an opinion on the Spectral Audio DMC-10 I'd love to hear that too!

Many thanks in advance
