You could also try MusicBrainz Picard for tagging, it free and very effective

I think it's because of the master/slave issue. A client dac I think can only have 1 master, but I would have to verify that with a bit of research, but essentially I think that's it. Having said that, aavik do have a pre amp with 2 dacs (pcm & dsd) and in their preliminary version it had 2 USB ports one for each dac. However, they did say in the production version there would only be 1 port.

Don't be afraid of it, it's not rocket science. To invoke it from Spotlight all you have to do is hit cmd space then start to type terminal and you will see it.

I don't know about DVD, but if you want to do a manual copy, avoid using the finder (way too slow). Use the terminal and use "cp -r <source path> <destination path>". Hope this is clear enough.

My intention is to ditch my whole setup, but because new turntable, phonostage, cartridge, dac, pre-amp & power-amp (and possibly power supply) is going to be expensive, I am considering my options very carefully; no rush. The problem is made worse, by manufacturers sometimes making wild/over exaggerated claims about their products so its a matter of sorting the wheat from the chaff. I was just hoping that there could be something I could buy relatively cheaply to improve my current setup until I have decided what I am going to buy for the longer term.

Ok thanks. I thought this might be the case, but its nice to get somebody elses opinion. Do you have any thoughts about power supply? I looked at that Project phono stage and noticed that they also sell an optional power supply. I'm quite skeptical about the usefulness of power supplies (that's only because I haven't done an AB test with/without a separate PS, but am open to it, if it genuinely affects sounds quality and in particular noise floor). Cheers.

Having just seen a couple of post recently about USB regenerators/filters, I was wondering (and hopeful) that I could use one of these such products (see link & attached pics below for examples) for an ADC audio interface. Now the interface in question is a Propellerheads Balance, which is designed primary for recording instruments such as electric guitar or Mic input via XLR. Now, my use case is slightly different but no less valid. I have a DJ mixer to which I connect a Technics SL1210 turntable and use this setup for digitising my vinyl collection at 24bit/96khz. There is a lot of noise in this setup which I am hoping to be able to reduce. This is not my end game set up; I intend to buy an audiophile turntable and phono stage (more research required before I'll commit my cash), but in the mean time, I would like some help reducing the noise I'm experiencing. I am using Propellerheads Reason as the DAW for recording and editing the audio, and it has a rather useful level meter. When all kit is connected but no audio playing, the meter is showing the noise floor is at around -60db, which is far too high. I think that most of this noise is coming from the analogue input via XLR from the mixer/phono stage; but I'm not sure how much of this is due to unpurified/unfiltered power supply going to mixer/phono stage and the turntable. Sellers of USB regenerators/filters would say that noise from host computer will infect any attached USB audio devices, but is this the case for ADC devices? Actually, the Propellerhead Balance is a DAC and ADC, but the usage scenario I'm focusing on is the ADC function. So can these type of USB purifiers/regenerators/filter devices help to reduce noise in this situation? (please see this link for device examples [ps, not the audio interface]: A Collection of USB Audio Enhancement Products | AudioStream ) Thanks.

Well I wasn't familiar with the 20% discharge limit, but I'll definitely keep that in mind going forward, so thanks for this little nugget of wisdom When time becomes a loop

Nope, you need to use the battery, it should charge and discharge on a regular basis to ensure long life on the battery. I found this out with my 2009 17" MBP, using it in the same way as you describe, and after about 2 years, the battery swelled up. Now, the battery was still fine, but because the battery has swelled, the extra pressure inside, broke one of the screws internally holding the battery in place and also the track pad buttons were no longer pressable. Apple genius guy said I needed to use battery power on a regular basis to prevent this happening. I've got a new 2014 MBP, and I now use the battery on a daily basis, in the hope that it will last longer without the swelling issue. When time becomes a loop

Thanks for the insight. Just have a question though. The way I'm currently recording is to adjust the line-in level on my mixer to the -1 Db level and then in Adobe Audition, I monitor the level there to ensure it doesn't go over -3 db (as advised by Adobe in their help documentation. In Adobe there is no opportunity to automatically set the level, which is what you alluded to previously. I remember when I was recording a while ago using Garage Band on OS-X, it would automatically set the level which is admirable. But I wouldn't use Garage Band because it only supports up to 16bit @44.1khz. So the conclusion I draw from your advice is that I should be dialling down the level on the mixer to -6db, but I don't quite know what you mean about adjusting digitally ('Final levels should be adjusted digitally'). My hunch is that you mean there may be a post recording process that can be applied that will boost the level up to the required level, but I don't know what this process may be. Cheers.

Great, thanks for that confirmation, it was what I was actually wanting to hear so that I can just justify buying some new hardware.

Well, that is a nice bit of kit, probably a bit more than I was looking to spend, something within the hundreds of pound range, not thousands! I am becoming convinced however, that an additional bit of external hardware will resolve my issues. Thanks. Oh and I forgot to mention that I'm using Windows 7 bootcamp on my Mac (OSX Snow Leopard has become dog slow), so core audio is not an element in my recording setup.

Thanks bplexico. This is the kind of info I was looking for; other peoples experiences of doing the conversion and their setups. Its is encouraging that you're using a Duet (I'm sure the other devices I mentioned will probably work too) and not experiencing the issues that I have. I do adjust the eq/output settings on my mixer meticulously so that that distortions do not occur and so this isn't actually an issue. A lot of the music I am recording is progressive house and trance which I intend to do DJ mixing with, so it is essential that there are no timing errors at all. I am going to read the guides referred to by Audio_ELF and hopefully I can pick up some more useful tips.

Nice looking guides, thanks for that.

I am currently recording my vinyl collection into high resolution Flac files currently using Adobe Audition but looking to buy Vinyl Studio if it can do all I need it to, which on first appearance looks like it can. However, I am looking for advice. My current setup is Technics SL 1210 MKII, Pioneer DJM-500 mixer, Mac Book Pro running windows 7. With this setup, I have discovered 2 major problems which means that the Vinyl I have recorded so far, will have to be discarded and I'll need to start over. The problems are: 1) Quite a lot of the recordings I have made are suffering scratchy type noises. At first I thought that it was because of a worn stylus, but when I listened to the audio from the source (IE headphones plugged into the mixer, the audio was flawless). So the these flaws were as a result of the analogue to digital conversion happening within the sound card of the Mac. I think this is what is called 'Clipping' but I am not sure. 2) I am finding that there are a lot of timing errors in the recorded audio. IE when you play back the audio, there can sometimes be a lot of micro jumps, almost like slight skipping as though small fractions of the audio were not recorded properly and thus are not in the resultant audio. I have tested on different devices and this happens consistently so I know its a problem with the recording itself rather than the playback. Now for both of these issues, I think that the problem is caused by the limited capability of the sound card in the Mac and I am guessing that I may be able to resolve both of these issues by using an offboard USB device (IE like an external soundcard). There are 3 products that I am thinking of purchasing: a) Propellaheads Balance USB Audio interface b) Tascam US-366 c) Apogee Duet I would like your expert opinion as to whether you think one of these type of devices will help in resolving the issues I have documented. Looking forward to hearing your views, thanks.
