I owned a Audiostore for a number of years getting 50%+ off on many items allows systems going into the $6 digit pricing
that being said I used to offer and have created system enhancers that do actually work quite well even in Highend systems such as my Duelund Audio purifiers
I took the summer off, that being said. Modding your electronics ,as well as Loudspeaker Xovers makes a dramatic improvement saving 2-3x the$$ vs New and without question better performance . Whati have found and please remember on average only 25% or less actually goes into the components or average ,the rest R&D overhead and markup, the Xover parts in a loudspeaker ,are at Best average ,worlds best Duelund capacitors you will Never see in any speaker ,why ?
great question ,there are many other very good caps like vh audio, Jantzen Alumen Z ,Jupiter ,Top Mundorf ,Milflex, ,clarity ,depending on the application each one sounds abit different, with resistors 98% use $2 ceramic resistors. The 2 best area Mundorfs Latest Ultra copper foil for absolute best detail ,2 nd isPath Audio-a bit warmer just slightly less detail , I have been modding for over 20 years learned a lot from Greats like Tony Gee ,Well known for his well know capacitor test book
Humblehomemade Hifi capacitor test. Speakers i mod mysel and coupling caps ,ifs it’s much more involved in electronics like Bellison regulators i hire a good tech .
save $10000s and get much better performance . Look for real good used quality and then have it modded by a good Audio tech that knows their stuff.
That's how Dan Modwright made his reputation.
