Someone online said there signs of cost cutting in stock form, such as poorly performing and noisey opamps in the preamplifier stage, and bad output connectors, these are easy to change and make a massive upgrade to the sound quality.

This person is not responding to me. I wonder if anyone else here is familiar with what he's talking about and if it's easy to change.
