The 1731 is a vintage-style opamp that colours more than the more clean, modern and milder saturation tract of the 918. Once again, you have the choice between two options at the output. The "Steel" variant has an iron winding core and presents itself as the more central, more strongly coloured variant. The "Nickel" option, on the other hand, has a 50% nickel content in the core and sounds a bit cleaner and more open in return. The "Vintage" setting activates two tantalum capacitors, the "Clean" setting two ordinary electrolytic capacitors - for even more sound variety!
