Hi guys I just found in local add of '
Mordaunt Short Avant 906i + 903i + 905i + 309i speakers'
Are they any good? The seller wants 330 for them and they are in excellent condition? I never heard of this company, to be honest

Spoiler

The seller also sells
Yamaha RX-V1900 7.1 Channel 130 Watt Receiver any views on that receiver?
Again I would be thankful for advice

The seller is asking 310 for the receiver. I tried to look online but no many people are selling stuff like that online
