No, the Bose analogy is way off.
If inside is arguably the best Blu-Ray player on the market, then sure - inquiring minds will need to know what they modified. If you're just using it as a digital transport, then there's likely nothing Lex could add to justify the price.
If you're using the analog outputs, then it gets more interesting in my opinion. Oppo's analog outputs sound flat and lifeless. They're my go-to brand for digital, but I'd never use their analog outs. Lexicon's analog outputs on their RT-10 and RT-20 sound wonderful. If your application would benefit from such, then it's a reasonable product.
Cheers.
