Ive never liked gain. ive used gain in various electronics through the years. and it always introduces distortion and other problems. I dont know about audio technology and maybe now its been so improved that its not a problem. but seeing no gain option on the RNHP is one of the things about it i liked. as well as no xlr.
XLR causes a number of problems for me. i now have to get xlr cables for my headphones. and thats expensive. especially with all the headphones i got. i’d rather just use the cables that came with them and the 1/4 connection. but if theres a xlr connection then i have to worry which one is better.
