Tube integrated comparison Cary SLI-80, Cayin, EE

I am considering getting a tube integrated amp in the future and would really like to know from people who have had a chance to listen to the following integrated amps to help out with opinions and advice. Are any of these able to equal the sound of separates in your opinion. I know the best method is hearing them for myself but that isn't always an option. I have gotten so much help on Audiogon that I really like to ask for assistance.

The integrateds that I am looking at for my system are Cary SLI-80 (also F1), Cayin 88T, Eastern Electric M520, (any others as good as these?).

This wouldn't be for a second system so I am really not looking to compromise performance. I have read that tube rolling in the Cayin & Eastern Electric can make them really sing. Any first hand experience with them?

Also intrigued by the Cary SLI-80 F1. Don't seem to find too much information about them other than on Upscale Audio website.

I need dynamics and crave the sweet midrange and highs that tubes can provide. My speakers are 4 ohm & 92db efficient. I would like a subwoofer output, remote, home theater bypass would be great.

Thanks for your assistance.
