How cam Morrow Audio keep offering 45%-65% discounts for trade-ups?

Because they use a dual overhead cam.

Morrow Audio cables are excellent cables FOR THE PRICE, but remember the MA4 interconnects (Mike Morrow suggests starting with the MA4s) are only $155 a pair with the sale. Will these compete with $500 or $1,000 cables? Most definitely not. But they do compete successfully with comparably priced high quality cables from DHLabs, Zavfino, Lavricables, and Supra......which are all great cables for their reasonable price; which I also own.

I own MA-4 interconnects (RCA and XLR), and their SP3 speaker cables, and they perform very well in my "mid fi" system. Calling Morrow cables crap is just plain ridiculous, and have you actually tested them? Eventually I will replace them as I upgrade the rest of my system for sure.

Cfarrow, you completely missed the thrust of my question.

 Are the trade-ins resold to cover the large discounts?

Or maybe you were referring to others who are bagging on Morrow?

I have owned several sets of ma3 and a dig2 and bought them on a BF Sale at 55% off and felt they sounded very good until I purchased the Aliexpress Chinese Nordost cables. Immediately sold the Morrows on ebay as they were nowhere near as revealing. As for the trade up I felt the math made no sense to trade in. Much better to wait and buy at 55-65% off and sell the old ones on your own. Were easy to resell them. Morrow is offering a convenience service and is happy $ when you upgrade. Personally not a fan of their fake sale marketing strategy. They are training us to only buy at 55-65% off and compressing the sales in limited windows which should impact/slow production/delivery times.

Pretty easy ,most of their raw material is from China 10-1 markup in many cables 

that’s how they can do that and stil make money , and their connectors 

inexpensive gold coated brass , unless you want to pay a premium .
