Al - insightful, as always. I have a Cary SLP 05 with a headphone amp output. How do you think it would match with the Line Streamer? What characteristic are you looking at to match the Line Streamer? I think most headphone amps have pretty low impedance compared to the Line Streamer input. Thanks.
Your choice for budget analog to digital converter
I am embarking on an effort to digitize my brother's vinyl collection for him. What do you recommend for a reasonably capable and priced (<$250) analog to digital converter? Would like at least 24/96 capability. I am doing it here and there so may eventually go through several generations of ADCs, but have start somewhere.
Rest of system: Thorens TD150 mkII, Grado platinum cartridge, Grado phono preamp, Dell Latitude laptop, Audacity software.
Any suggestions appreciated.
PS - in case you are wondering why he is going digital, he is a musician and wants to take his music collection on the road. I get to keep the vinyl, but the time is really a gift. Your time is too, thanks. kn

Dtc, thanks. Yes, all or nearly all headphone amps will have output impedances that are easily low enough to be able to drive 5K with good results. And that is confirmed in the case of the SLP-05 by the indication in its manual that it is suitable for use with headphones having impedances of 30 to 300 ohms. (The reason headphones with higher impedances may not be suitable is undoubtedly due to limitations on output voltage, not output impedance). The line-level main output of the SLP-05, btw, would not be suitable, as its impedance is too high to drive 5K with good results, perJohn Atkinson's measurements. The other thing to consider is if the headphone output can provide enough voltage to the Linestreamer. I see in its manual a statement that it can provide 0.5 watts per channel. Making the worst case assumption that that is based on a 30 ohm load, that corresponds to about 3.9 volts, which would be fine (when reduced by the preamp's volume control). A point to be aware of, that is mentioned in the manual, is that apparently the preamp's main outputs remain active when its headphone amp is switched on, so the power amp would have to be turned off if you don't want sound from the speakers while you are using the ADC. Just pick up an adapter like this, and I'm pretty certain you'll have no problems interfacing to the Linestreamer. Regards, -- Al |
Al - thanks, that all makes sense. I am aware of the high impedance of the main outputs, but it is not problem for my Levinson 432. Actually, I would probably want the mains on when recording if possible. That would depend on output levels. I really wanted a Korg MR 2000s but I procrastinated too long and they have been discontinued. I am also looking at a Korg MR 2, partially because of its DSD capability. Unfortunately, the Ayre is a little rich for my blood, at least at this point. The idea was to use the Line Streamer as a starter unit to test the process, but I have not pursued it because of the lack of volume control. You headphone amp suggestion is a good one that may get me back on track. Thanks. |
