Audio Research reference amplifiers used with RCA IC`s and unbalanced preamplifiers

I am considering purchasing used audio research reference amplifiers either 150se or 75 SE. My question is this

As these amplifiers are fully balanced and don't have an RCA input, can I use RCA interconnects with a conversion plug from RCA to balanced at the amplifier input and will it work in my system?

I don't have any balanced interconnects and don't want to go through the extra expense. Only one of my three preamplifiers has an XLR output and there's nothing indicating the preamplifier is fully balanced.

I find this balanced/ unbalanced criteria confusing.

my preamps output impedances are as follows:

200 ohms from the Wavestream Kinetics

150 ohms from the Wyetech Ruby

3500 ohms from the updated /customized Counterpoint SA5000

Thanks. I agree it's a good idea to contact ARC directly and will do so as their answer will be definitive. 

Just curious how much wattage do your 75se and 150se put out in triode mode?

cant seem to find any data on this.

Thanks , Sounds like your fully balanced from source to speakers. Will take a look at your system.

Does anyone have experience with ARC latest iteration , the Reference 80se amplifier at 70 watts/channel as compared to the Reference 75SE soundwise? 

THE REF 80SE has rca inputs on the unit so I guess using RCA IC's would not be a problem?

Also, Kalvin is not retired and is at ARC and is usually the guy who answers the phone.

@speedthrills I went to Ward's funeral (RIP, Ward) a couple of years ago and saw Kalvin there. He told me he had left ARC a couple of years earlier. If he has since gone back that is news to me.

@nsp Of course- no worries!
