Assuredly a very good phono equaliser. It's a serious product and far from the (miserable) stuff usually available. Whether it's the best, I wouldn't know and, frankly, I couldn't know (how would I judge that:)).
It's unfortunate that at its price (25?30k?) it doesn't include an inverse riaa s/where at one of the inputs.
It's appropriately versatile of course and you also have access to different -- non riaa -- equalisation curves which is very useful if you have vintage LPs (you get a different small circuit board of sorts). They cost extra but aren't ruinous afaik.
It's a very complicated circuit, btw, and don't even think of "tweaking" or "improving"... If anything, ask Boulder to provide whatever tickles yr fancy (i.e. if you want to do away with the 75us pole or play with the idea of a 3,18us, I think) -- at the price, Boulder can easily oblige.
FOr that matter, FM Acoustics also offer an excellent phono equaliser which is less ruinously expensive. There are a few other stratospheric phonos too (most of which I haven;t heard) -- reportedly, one of these made by an A'gon member (Raul -- there's a thread about it). Cheers
