Excellent condition Topping D90 in black for sale.

Asking $525 nett to me, shipping and paypal fees additional. Price is firm, this is not a fire sale. It takes time to respond to tire-kicking lowball offers - seek your kind understanding.
I have good feedback on here, Audiogon, Head-fi forums, Ebay. Let me know if you need references.

I accept PayPal goods option (2.9% extra), PayPal friends and family, venmo, money order, check.

Shipping via UPS at cost, I have a corporate account, about 40% off retail rates or more depending on location. Contact me for a quote for most accurate numbers. Shipping to lower 48 states fully insured averages around $30.

Pick up from downtown Chicago possible, I live right by Water Tower Place.
