If need be, where can one purchase rca input connector block for Leben 300x? I have one channel on input that does not do the best job of accepting the interconnect. Since there are effectively six inputs including tape monitor, I can live with this but eventually would like to take care of...

Got it to work w addition of AC phone charger lightning cable connected to the camera adapter lightning input, other end connected to AC wall outlet through the USB wall outlet adapter ). A little finicky in that Tidal or TuneIn don’t want to always connect, but eventually they did. Not the...

Power supply for the DAC or for the phone (the lightning to usb 3 camera adapter has an input to attach AC phone charger), or both? What specific power supply are you using?...thank you, Don

I just tried it. Does not work. I have two different lightning to USB adapters. One is the usb camera 3 adapter and the other is just the direct lightning to usb. From TIDAL streaming, The former gives no message - Tidal just keeps shutting off. The latter actually gives a message on the...

J just tried it w iPhone 7 via lightning to usb. No power supply. Will NOT work.

Hello I want to use iPhone 7 streaming Tidal as the source for this DAC. It is unclear to me how to connect and power it using lightning to usb 3 camera adapter and what additional cable adapters are necessary. I assume that the IPhone CANNOT provide the required power to the DAC. Then I...

Hi Does someone have an owners manual for the 300x that they can email to me? I also trying to determine the origin of hammond-labeled el84s that are in this amp. Thanks Don Donroth45@yahoo.com

Definitely out of the picture for me at that price but there were other issues as well for us 2-channel audiophiles anyhow.

I saw that on the website too. So the email (from within last two months) seemed to contradict that. They should clarify all this.

From James: Hi Don, No, A16 measurements will not be usable on the A8. And A8 measurements will not be usable on A16. Regards James

In an email from a Smyth, I was told no backward or forward compatibility between A8 and A16 files.

Hard to believe DEQX has not gotten into this game.

Yes of course. This is what I am after and would be the first in line for just this wo all the hardware and software bells and whistles. Would pay well for files associated with a number of the high end stereo speaker setups at a manufacturer or dealer site if they would be open to this (and...

Your points are well taken. Seems like a streamlined product focused on high quality 2d stereo simulation without all the bells and whistles is what I am after. Ultimately, maybe it could be built directly into headphones.

We need a product similar to the Smyth device that is completely focused on simulation of very high quality 2-channel music reproduction. I, like some others here, have no interest in special effects (explosions, gunfire, thunder, automobile noise) being located accurately in front, behind, or...

The iphone has a digital out that can be made usb via an adapter. This is how it attaches to the dragonfly red dac from audioquest. This dac has an analog out which can be connected to line level inputs of an integrated amp (this is what I do) or directly to headphones. I know some of the...

I really appreciate you taking the time to provide your experience. I now know I need more time to evaluate this product for the purposes of high quality 2-channel reproduction.

Thanks. Like you, I am only interested in this device for 2-channel stereo. I am contemplating an order, but I still have not figured out if this device has its own dac (usb input) and if one can use their own amplifier or if the a16 utilizes an internal good quality amplifier. I do not want...

For the sake of completeness, I forgot to list the power cord in the parts list:   Cables To Go 03130 18 AWG Universal Power Cord, IEC320C13 to NEMA 5-15P (6 Feet)   Also, this cord is connected from the adapter into the isolation transformer, which is then connected to the AC outlet.  ...

Guys -   I did take some safety precautions and I am sorry that I did not list them or take a photo after I did them.  I wrote the article from memory a few weeks ago after having completed the project in April (about 9 months difference between project completion and writing the article). ...

High-Quality Stax Headphone Adapter By Don Roth and Birgir Guðjónsson   This project allows one to build a very high quality version of the Stax SRD-7MkII headphone adapter to allow one to use an existing favorite amplifier to power your stax headphones. (Let Birgir know what amplifier...
