phono preamp for the ortofon 2m bronze

I bought my 2m bronze  late 2016 - early 2017. yes I am not jumping to buy a power supply yet, but my wheels are all ways turning and I enjoy researching equipment and upgrades. I do not buy unless I do all my home work / research . in this hobby it is very easy to go in the wrong direction  fast . thanks

kully560,

The Arcam at 40db will multiple the input signal 100:1, so a nominal input of 5.5 mv will output at 0.55 volts.  The nominal signal ended output from a cd player per redbook is 2 volts.  So, the Arcam will need more volume.  I did a quick look at your 14B3 amp, and it has a two gain settings. High sensitivity 23db which is 1V for 100watts, or low sensitivity 29db which is 2V for 100watts.  If your volume is 2/3 with cd, is the amp set for 29db?  If yes, setting to the 23db high sensitivity may give more volume control, just a thought.

hi antinn I believe you have it reversed the 29db for 1v most amp gain and the 23db for 2v. the owners manual recommends which I run balanced cables is the 23db gain setting [ noise -119db]. the singled ended [rca] is 29db for 1v [noise of -115db]. I use all balanced cables and also aes/ebu digital cable.I found these sound the best for my system. I may flip my gain setting to the 29db and leave my sub woofers off and see how it sounds . I all ways new the vinyl will play at a lower volume but is should not be at 1/3 more on the volume control .thanks for checking for me I let you know how that works out. also on a side note to the linear power supply. my research came up with the r-core transformer being much better than the toroidal transformer type so it seems .

hi antinn, thanks for all the help and suggestions . it work out well at the 29 db gain setting much more control over all on all sources. my cd player is at 1/2 volume and the turntable is at 3/4 volume much better . it seems that I have more authority to my speakers [ little more punch] very happy now . I also rebalanced my subs and was able to lower the crossover point from 60 hertz to 48 hertz . my speakers roll off at 48 hertz anyway . if I further decide to build or buy a linear power supply and try it I will let you know how it works out . king regards kully

Kully,

Good to hear it all worked out.  For a linear power source with R-core transformer, check out Wyred 4 Sound`s, PS-1 modular linear power supply.  The version with one high current (3A) module which would be required for the rPhono, is only $799 🤔
