The problem with the 271 for topic starter is that he needs coax out for his speakers and not speakerlink outputs.
For me it would be a solution but the price here is 3750 euro and haven't seen them second hand.
Like topicstarter I have an 218 and a Distributor 3 so 8 channels can be used with an analoque preamplifier. For most people that is enough.
Could not justify to spend 2850 euro more on a 271 for that. Here in The Netherlands it is olso hard to find a dealer for new or used gear. So mostly has to come out of other countries. There are some good dealers in the UK and within the EER region. The last is most handy for the people within Europe. We can buy there without paying import taxes.
