What kind of power cord comes with expensive gear

Quality power chords are required.

Ibought the REGA ISIS valve cdp and REGA OSIRIS integrated amp this past year. Each came bundled with a high-end power chord custom made for REGA by hi-end mfg. Klotz in Germany.

With the REGA kit, these bundled power cables actually outperform my other hi-end power chords terminated with either the top-of-the-line gold-plated FURUTECH or OYAIDE connectors.

The latter are crackin' good power chords by any standard (I've swapped them in and out with the REGAs)...it's just that the factory supplied REGAs work better with the REGA gear.

" ....it makes sense to provide an inexpensive power cord with any component. audiophiles like to tune their systems with after-market power cords...."

Not Always ....

REGA, LFD, and NAIM are among the few that provide (and recommend) their own high-end power cables for their high-end gear. As it was explained to me in general terms, they design / "custom tune" them for their kit.

Personally, the power cables that came bundled with my new REGA OSIRIS amp and ISIS cdp gear is a $200 - $300 range product custom made for them by KLOTZ in Germany. Top shelf construction here - nothing cheap here.

NAIM even has one much, much higher in the $$ range for their kit.

I was initially skeptical. Ultimately I was very pleasantly surprised that they out-performed my other expensive after-market OYAIDE, ECOSSE, and FURUTECH cables modded with their very expensive top gold plated connectors.

Again, the latter cords are still killer power cords in their own right that take on most comers; it's just that the REGA high-end cords worked best with the REGA gear.

These other power cables I faithfully still use as replacements in my B system and in my AV system with stellar results.

FWIW....
