Preamp Rectifier Tube Confusion

Ralph... I think the world of you and have learned very much from you over the years.

I just posted what was written in the review.  However, I have sold, (as a dealer) and owned, (personally), quite a few preamps that have had tube rectified power supplies.  I have found without question, that I could change the sound by replacing the tube rectifier.  If this indeed due to a voltage increase or decrease, so be it, but it did and does change the sound.

I'm sure it does! But that is the only reason they make a difference- and if its all about getting the best sound, you can do better than that by going solid state (and making sure that the circuit and power transformer are happy with the increased current draw) as long as the rectifier/transformer combo doesn't make noise- if it does, there are way of shutting it up.


Every time you think you've surpassed the penultimate, it turns out not to be the case- there's *always* a next step.

Philips 5R4GYS in the house! Beautiful glass...haven’t had time to give them a critical listen.

just don't let the eyes fool the ears

bling and good sound are separate departments, need separation of powers  :)

I have my 3 favorite recording’s that are superb at demonstrating vocals, soundstage and separation. They also do the magic act and make the KEF Q150’s disappear...if I can’t hear a difference then I’ll chalk up the 5R4GYS to pure aesthetics. 🤷🏼‍♂️
