If you bought them ,and missing grills without question they should send you a return shipping label and return shipping
without question ,did you pay the shipping ? As a ex audio consultant ,and Audiophile
they get a credit if it’s a mistake on their part .
upscale audio from my experience is Not good at all on Discounts
and I had bad tube out of a quad where they said close match tested ,it was 30% off and turned a cherry red , I had to pay the freight back ,I sent them all back , they would not refund me ,and I had to file a claim with my credit card company , prima luna also
after 2 weeks a resistor took out the integrated amp , you would think with less then 2 weeks they would just send me a new one ,
no way I had to send it back and wait, I personally would not buy
any more Chinese junk again from them ,I only buy 🇺🇸 or Europe or Japan You get what you pay for !! I am only speaking for myself .
