How about you wait a few days for someone to reply to your topic?

For preamp, I'm checking this one out (or simmilar):
http://denonpro.com/products/view/dn-500av
I have active speakers, so I don't neet amplifier, but preamp. Considering I need HDMI inputs, too, I'd rather buy something like this, than something from those companies that sell gold-plated quantuum transformers in their equipment...

According to
http://www.avc.hr/salesprogram/files/db_files/files/denon-um-dn500av.pdf

The relevant specs are:  Output (+4 mode) 318 mv or 0.318 volts.  IOW this device appears to be is in trouble with just about any industry standard power amp, consumer or professional. I'll bet that there is an amp from the vendor that works, though! :-)

Support - (fb2k) / CD Ripping Problems
Last post by Rizado96 -
Hey all,
I'm having a weird issue with ripping CDs. It seems to read the first track, but then keeps ripping and overwriting that same track over and over, so at the end of the rip I still only have one file. I've tried to rip with both FLAC and LAME MP3 encoders, but the issue persists with both. I've tried some quick searches, but I can't find anyone with the same problem. I don't know what could be wrong; It's never done this before. I'm running v. 1.3.17 and Windows 10, and my CD drive is a USB Apple SuperDrive. Below is my list of components copied from the preferences pane. If there's any more info I can provide that will help, just let me know. Thanks in advance!

Vinyl / Re: 33 vs 45rpm -- Technical Differences
Last post by Atmasphere -

This thread was first prompted by my seeing several 'audiophile' releases of albums, where a typical LP had been spread across two 45rpm records on account of its purported benefits to sound quality. Audiophile claims are nebulous at the best of times, but knowing more about digital audio, I wasn't sure if there might be something to this one.  :D

There could be, if the groove modulation is also higher. There is certainly the room for it. Quite often though on such reissues, the master tape has degraded as they do over time. But it might be worth a listen, especially if the original is not available.

General Audio / Re: Advice on transformer hum
Last post by Atmasphere -
Atmasphere - thanks for the interesting thoughts. I have no experience of isometrically mounting anything. What you describe sounds like it may be worth a try, though it also sounds like a reasonable amount of work. I had already removed the transformer mounting screws and placed the transformer on top of a relatively thin bit of rubber - which made little difference once the case was back on. Is the technique which you described likely to yield substantial improvements over this?


No. That suggests that the toroid is making the vibration, not the smaller EI core.

Stay warm!

Opus / Re: Opus 1.3-beta is here
Last post by jmvalin -
Yes, see my previous posts in this topic.
1.3b and 95c4871 are no-go at 32 kbps.  1.2.1  hasn't perfect speech/music switching but  right now is the best (as for my ears)
Note that the 95c4871 build is just some point early in the 1.3 development, before some of the speech-related changes. I'll get back to you later on this. In the mean time, I've come across some TF-related issues and made some builds for testing:
This is intended to improve on samples that mix tones and transients, e.g. the #41 intro. I'd be interested in feedback about how it improves and/or makes things worse.

Thanks for the further replies.

I understand that there are many differences of opinion regarding DACs (and indeed other components, leaving alone cables), and tempting as it is to behave otherwise, my intention here was not to get drawn into a debate on the relative merits of the various implementations. I would rather stay on track with the issue of the hum/buzz if possible - though thanks for the food for thought.

I was planning to take the DAC to an audio store for further investigation tomorrow, though a snowfall has meant that sledging with the kids may take priority and this will have to wait until next week :)

Vinyl / Re: 33 vs 45rpm -- Technical Differences

Faster rotation, more noise and more noise spectra at higher (typically more audible) frequencies.  Working against that is the fact that higher effective linear speed of groove tracking makes the same groove produce more electrical signal with velocity-sensitive pickups.

Interesting. Do you know of any research/texts looking at relative performance of the two speeds? I'm particularly keen to see how the factors you've mentioned typically net -- that is, is it safe to assume that most music pressed at 45rpm will, ceterus parabis, yield less audible noise than if they were pressed at 33rpm?
