I cannot imagine having a new component and missing out on whatever transformation it could make over time. That is your new preamp in your system in your room playing for your ears. Who cares what everyone else says or thinks...you decide what happens after 100 hours, 400 hours and so on.
I have only purchased used equipment so everything has always been fully burned in and I never knew if it was a bunch of BS. Well, I got my Audio Research REF 160M amps upgraded to MkII a few months ago. When I got them back and set them up my heart sank. They sounded a bit shrill and bright to me and I am uber sensitive to bright sounds. I was sick to my stomach...what the hell just happened. I called them and they just assumed I knew....with all the new caps and wire they need about 200 hours. Sure enough, I could hear the sound evolving and all that bright sound disappeared.
I hope your new preamp works out for you!
I’ve taken a slightly different tact with the most recent additions, collecting pieces at the more moderately priced end of the spectrum and looking for sales, open box and well-loved to save a few bucks here and there to acquire components that have for a long time pique my interest. Suprizingly, budget components have come a long way and seem to be configured quite intelligently delivering all the attributes audiophiles seek for music reproduction. The Rotel, Teac and the Dali’s with Audio Technica VM95 and the Rotel’s phono stage is absolutely amazing for what it is! Of course, the Naim and Spendors require all the advantages of my best source components and deliver accordingly. Fun stuff!
