Phono Preamp Reviews

As long as you're spinning an LP for your listening pleasure, and if digitizing it at a resolution of 24-bit/192kHz is transparent to the analog source, why not record and store the LP on your computer at that high sampling rate for future convenient playback via iTunes or for iPod use, or for burning to CD-R? And, while you're at it, why not record the LP unequalized and apply the RIAA curve in the digital domain, where you're not dependent on capacitors and resistors that are imprecise to begin with, and can drift over time? With no drift of phase or value, the virtual filter's results should be better than with any analog filter. And in the digital domain, you can program in any curve known, and select it at the click of a mouse. Aside from the sweat equity invested in programming it in the first place, it wouldn't add a penny to the program's cost.

The minuscule electrical output of an analog signal from a moving-coil cartridge needs to be boosted before it can be converted to digital and equalized in the digital domain. Of course, you could use your current phono preamplifier and record an equalized signal to hard disk, but then you wouldn't get to experience Pure">http://www.stereophile.com/computeraudio/pure_vinyl_lp_recording_amp_ed… Vinyl's digital RIAA correction—nor would you be able to avail yourself of all the equalization curves provide by Pure Vinyl, of which there are almost too many to count.

The best result of mathematics is to not need it.—Oliver Heaviside, 1850–1925

Not being fond of self-flagellation, I don't usually do analog. I am not a fuddy-dudley, nor am I especially fremerous.

In an ideal world, I'd have every phono section I've reviewed in the past 16 years on hand to compare with these three and with all that arrive in the future. But because I have a life, I don't, and I wouldn't even if I could, though some readers (and one retailer) have insisted that that's the only way that I could possibly be of any use to them. Ha! And for those who are concerned that I've neglected the Manley Steelhead, not so! It's still my reference.

I first spotted Audia Flight's exquisite-looking two-box phono preamplifier ($6100) at last year's Hi-End show in Munich, and now that Musical Sounds is importing Audia Flight gear, a review of the Phono seemed a good idea. I know nothing about Audia Flight or the designer, or what Italian audiophiles think of them, but the more time I spent with the versatile, exquisitely built Phono, the more I liked everything about it.
