Hi GAZ19
Thanks for your reply.
I've not found a combination of ATC monitors and Cyrus electronics to bright, harsh or glaring. The bottom line is the ATC's are effectively flat and honest so therefore they'll pretty much reveal the qualities of your recordings, electronics and cabling with practically no colouring/rounding/smoothing.
I hate to say it but if you're not sure than the only way to know whether the ATC's accuracy suits you is by listening to them.
All the best
