Based on all the rave reviews, I am considering building this phono stage. I saw a post on Audio Talk (a UK audio site) that may or may not be of concern. The thread starter was building the LR Phono and, at page 3 of the thread, posted his frequency response (https://www.audio-talk.co.uk/phpBB2/viewtopic.php?t=8198&start=30) (see posts 30 and 40). It seems in his case, the highs and lows were down considerably. He solved the problem by changing a resistor value. He attributed the problem to a possible defect in his inductors. Has anyone experienced anything similar. I believe he used the same cinemags that are in the BOM. Is this something I should be worried about?
Thanks for any assistance anyone can provide.

I really had no complaints and I would say that it came up in #2 position of the several phono preamp that I bought or built. It was just there and that was step above the ones that made themselves known with their presentation. I built two PM phono preamps. It just happened that way. Would be good for you to check out using a battery supply if you want to get into that sort of thing.
Yes, in fact that is a part of the longer story. I got to building the first one and then waited on the damned inductors for too long. I don't remember exactly why, but somehow, another set of inductors was ordered. Some kind of misunderstanding on their end. Didn't matter, I went ahead and built another with the intent of selling one and keeping one. Too long a story but the original attempt to build a fantastic phono preamp finally came through. Well, time to sell all the other phono preamps in my little batch (4 to be exact. Ranging from $300-600). I learned a lot but will tell you that it cost a hell of a lot more to build a better sounding phono preamp. That particular phono preamp ending up costing about $1,500. Another long behind that cost too. I can say that is what I went through in a 2 year course of time.
