Receiver


Hi all, 1st time ever to any forum and full disclosure I am a total novice in the audiophile world, that being said, I am looking for recommendations for a 8K receiver to power the following unpopular speaker in the USA, Vienna acoustics. I have a total of 7 speakers (4) Grand bookshelf 6ohm (2) Waltz 4ohm and (1) maestro center channel 6ohm. I am currently using an older Marantz SR7005 but since I purchased a 4K TV I am looking to upgrade!
thank you in advance

 NAD and Anthem are my only two realistic choices right now. Anthem is in the middle of a product change, so you may find the MRX line at a discount as they roll out their latest.


I wouldn't put any consideration into "8K" stuff.  It's really just the next marketing gimmick to "sell" consumers into buying new equipment.  Realistically, in some situations, you really don't even need 4K. 
Am I doing something wrong? I have a 65" 4k TV and tube amps in 2 channels with a sub...
