post #8401 of 10997

I was checking out 7N7 tubes it seems those are electrically the same as 6SN7 tubes so in the Littledot they could only be used as power tubes right with  7N7 loctal to 6CG7 adapters am i right and do they sound better  than the 6SN7.Also tempted to try them in WA6 Jac music sells the adapters and tubes are cheap .Those tubes worth it you think . Thanks.

Hi Mikelap, generic ASIO with ASIO4ALL works fine for playing 96 kHz files with Musicbee and I can use WASAPI with AIMP3 and Foobar at 96 kHz without issues. Yes, it is set to 24 Bit with 96 kHz, which is apparently the max for the M-DAC. I will try the hardware mixing but I am not inclined to do the upsampling. Thanks for coming back on this topic.

Hi MIKELAP.

 

I personally preferred them to even a nice pair of VT231s, and they do get a good bit of praise from various quarters...:p

Hi Mikelap, hardware mixing didn't do it but I can use WASAPI if I set the resampling rate to 48 kHz, resampling to 96 kHz would always produce the crackling background noises. Now, I am trying ASIO4ALL, which apparently is Kernel streaming, at 96 kHz and WASAPI resampled to 48 kHz, which in theory should be worse but doesn't appear so far worse maybe because WASAPI is superior.

 

I have got this from the Jriver Support page, might be interesting for everyone:

 

Choosing the Audio Output Mode

On OS X MC uses Core Audio to access your audio device, which provides bit-perfect playback, and requires no configuration. On Windows, Media Center will typically choose the best Output Mode available for your device, based on the drivers installed. If given the choice between multiple modes or drivers, choose the best output for your hardware in this order:

1) If your hardware has a native, well-behaved, ASIO driver, use ASIO.

2) Otherwise, on Windows Vista, Windows 7, or newer, use WASAPI Exclusive Access.

3) Otherwise, use Kernel Streaming if it works.

4) If none of the above are possible, use DirectSound or WaveOut. Neither of these provide hardware direct output, so choose based on performance.

If you have problems, start with DirectSound and get MC working. Once you have audio working and are comfortable using MC, then experiment with other audio output choices.

 

ASIO

See also: ASIO

ASIO is a sound card communication system created by Steinberg.

If your soundcard has a native ASIO driver, this is the most direct (and normally best) way to communicate with it.

Please note that ASIO4All is basically Kernel Streaming with an ASIO wrapper. There's no good reason to use ASIO + ASIO4All vs just using Kernel Streaming directly in Media Center.

 

WASAPI (Windows Audio Session API)

See also: WASAPI

WASAPI is a hardware communication system in Vista, Windows 7, and newer. When used in exclusive mode, the Windows system mixer is bypassed.

 

Kernel Streaming

Kernel Streaming is a hardware direct way to speak directly to a WDM audio driver. It works on XP, so is useful when the above two options are not possible.

 

Direct Sound

This is Windows default and the most compatible output method. It plays through the system mixer. This means all formats will be converted by Windows to the native format of the card. It is highly compatible, but it is not the highest quality method.

 

Wave Out

This is a legacy output mode. With some misbehaved hardware, it may work better than DirectSound.

 

Disk Writer

This writes whatever would have gone to the soundcard to a WAV file on disk.

Electrically, they are identical to 6SN7's, but of course, they require a loctal socket instead of octal. The vast majority of 7N7s were manufactured by Sylvania, but occasionally you will find tubes manufactured by National Union. In my experience, the Sylvania's sound quite close to the short bottle 6SN7GT/A Chrome Domes. So yes, they are quite good. However, in my opinion, if you already have a pair of Chrome Domes, the 7N7s are probably not worth the extra cost of the adapters.

 

On the other hand, if you are itching to try 7N7s, you could also try 7AF7s, which are the loctal version of the 6SL7. As a driver, I liked this tube better than the 7N7s, but can't say how it might perform as a power tube.

In Musicbee if your Dac supports ASIO  if you choose ASIO you see configure you click on that a screen appears you see CONFIGURE again click on that  a small screen appears on there you can ajust latency  this is usually done when tune stutters maybe would help your problem

Hi Mikelap, thanks for the hint. With ASIO4ALL, everything works fine, even both Audiolab Bitperfect tests pass. Of course it doesn't pass with resampled WASAPI. My guess is that it is a random MDAC incompatibility issue with Musicbee, that just pops up at 96 kHz and with WASAPI.

That is why we run Foobar2K, It just works.

 

Or Fidelia if your from the other side of the tracks...

Hi Mikelap,

 

"was checking out 7N7 tubes it seems those are electrically the same as 6SN7 tubes so in the Littledot they could only be used as power tubes?"

 

I have used 6SN7 tubes as driver tubes using a breadboard and Vector adapters. If you have a loctal breadboard adapter the 7N7 should work just fine (and the same goes for the 7AF7).

Cheers Trolldragon. Foobar2k works fine but it doesn't sound as good as AIMP3 or, checking that at the moment, Musicbee.

 

+1 for Kiss, Detroit Rock City :dt880smile:

Won't go down that road on the sound of players, I followed that silliness for a while in the J River threads...:D

 

The player should be the most transparent item in the chain unless you add features that muck with the sound. 

 

 

Enjoy AIMP3 and MusicBee!

I also use AIMP3, very happy with it. great upgrade from the standard windows media player which I was previously using :D

+1 Foobar 2K and TEAC UD H-01 sound amazing.
