Digital RIAA alive and well on Windows
I have to disagree. Digital RIAA is quite doable.
Starting from the principle that you don't really need 47K for a moving iron or moving magnet, 1K will do (I use 18K), this opens up MANY possibilities. VERY high quality mic preamps can then be used which have specs that are found in very expensive phono stages.
Have had this archived in my email for some time from AA:
"As the load impedance approaches the DC resistance of the cartirdge the damping effect is much greater for a slight reduction in impedance but as you go the other direction the source impedance is so low, relatively speaking and inthis case less than 40 ohms, the ratio of source to load is already very small at 1000 ohms and is reaching the point of diminishing returns. an incease to 5K or 47k doesn't do much. 47K was a convenient value but 1K would have been just as good for most MMs. "
You don't want to do any gain, if possible, in software, then you are working (i.e. digital RIAA and noise reduction) in the low end of 32bits. Common knowledge as AnalogNut stated, but there are ribbon mic preamps out there with incredible neutrality and tons of gain. So the gear is used for said purpose, it's out there at various price points and the impedance on many will work if you have something with low relatively low internal impedance like a Grado (Reference Statement has 2ohm).
I have found the AEA TRP to be ideal for digital RIAA implementation. Using MG-1 tonearm and Grado Reference Statement (.5mv) I do about 70db with the AEA. I was using a Lavry DA-10 but have settled on just using the sound card (1616M); the front end is probably more important here.
On Windows, you'll need something like Samplitude (or any VST capable app) and run the IEEQ plug-in from Jiittee at head-fi which he claims (and shows some math) is as good as Orban's PurVinyl filter which is VERY good.
I run [b]realtime [/b]32/96 recording and monitoring (simultaneous) with a touch of Algorithmix noise reduction. You can add butterworth etc with other plugs.
Some of the software I have noted is not cheap but if you search Head-Fi you'll find a completely free implementation using Max. You just need to get some decent hardware. The ART Gold mic preamps (tube hybrid) offer a ton of gain and also have the exact same ADC chip that is in the dedicated EMU 1212/1616 sound cards.
Lots of fun and sounds great!

FS: Cyber 211, Lavry DA10, AD10, AEA TRP ribbon, tons of gear
I'm rebuilding my system over the next 4 months due to losing my music room so I will be selling most of my equipment.
I'm looking for:
Decware mini-Torii
Wavelength Proton
EMU 1616 w/ PCMCIA card
Core-Sound 2496 V2
I'll be parting with:
[LIST=1]
[*]Lavry Lavry AD10 purchased 6 months ago from Sonic Circus 1180 shipped
[*]Lavry DA10 purchased 6 months ago from Sonic Circus w/ 1m Van Den Hul Optocoupler (sold together) 860 shipped
[*]AEA TRP "Big Ribbon" mic-pre purchased 6 months ago from Sonic Circus 775 shipped
[*]EMU1212M - well kept always behind a Brickwall $80 shipped
[*]5687/6BQ5 integrated amp 625 shipped -
Apparently the front end on this amp was designed by Gary Dodd of Dodd Audio. The builder is Charles Cicci and I have his phone number. I can do 625 shipped on this with a matched quad of RCA bronze plate 5687, and a matched quad of brand new Genalex (re-issue) EL84. I use an Amplitrex AT1000 to test my tubes. I simply don't have room for this thing in my new space.
Here's what I have from the previous owner, a friend of Charles (a really nice down to earth guy).
"Teflon-insulated wiring, good RCAs, instrument-grade biding posts. PRP non-inductive resistors and a variety of good caps. TKD volume control. Hefty input selector switch.
Retrofitted McIntosh chassis. The tube cage is included.
Awesome input stage, with 5687 tubes. (7044s will also work.). And those are Bugle Boy 6BQ5’s in the output stage. .
Output power is typical for an EL84/6BQ5 push-pull amp, probably a substantial 15wpc.
This amp has a regulated power supply—which is pretty unusual for a power amp stage. It’s built on the heat sink that’s visible on top of the chassis. The power transformer is somewhat oversized, so it has no trouble handling the extra current draw through the regulator.
As for the sound, first of all, it’s the quietest tube amp I’ve ever heard—probably because of the regulated power supply. It isn’t quite as lush as you might expect from an EL84… It’s airier. Vocals have more air around them, and it nevertheless has a characteristic EL84 sound. It does sound a little warmer with the Bugle Boys than with the TAD EL84’s I have. The TADs are also a nice tube. I’ll include either set, buyers choice.
Built by Charles Cocci in Brockton, MA. (He builds a small number of tube amp, preamps and integrateds, and also mods lots of audio gear. He might be better known, except that there’s a fairly small number of us who buy up most of the equipment he builds.) "

New HTPC
Getting ready to build a new HTPC out of a ITX board and Psile case. Should be interesting.
