(Pro 7.1) Exceeded expectation!! Sound quality is very good. Has added a new dimension to watching movies. This system replaced a Sony sound bar of equal price, no comparison/significantly better. No regrets and would purchase again. Only issue is that Amazon placed the system on sale for $70 less 2 days after my purchase... disappointing. I also attempted to perform the software upgrade but not sure it was successful and it doesn’t appear you can validate version. All in all good product. I would definitely purchase without hesitation for $579, Presidents’ Day sale price... Enjoy!!
