It is limited to the ability of the computer it is attached to, Mac Laptop 192. I have an outboard DAC that allows it to go to 350 pull and with a filter 700.

Why would a free eq program need your access key to your computer?

I know there is another link on Fidelia, but why is it not talked about on this link?

I notice you have a benchmark DAC. How to you like it, and have you head any of the Chord products?

Thanks for your reply. I am considering getting the Isine over the SIne, and wondering which one. Did you check the equalization on your Iphone to see if it was flat? Or did you listen to the two of them without the lighting cable. If the Isine 20 was bassy even with a bad fit that mean more...

No one had said anything about the difference between the Isine 10 and the Isine 20 that make the later worth $200 dollars more. I heard it described as smoother, and more detailed but..... I have heard the Sine and the Titanium, and there is a difference in presence, or mid-range due to the...

I just receive my uDSD, and I am very impressed. I have the uDac2 and uDac3 compare it to, and will have to give up uDac2 to get the discount for this new uDSD. The progression amazing, and a pleasure. There is only surprise  is volume knob logarithmic progression. I had to turn it up past the...

Try a pair of Kline hummel, they are now part of Neumann group of professional products. There is a range of them by the KH-120a would be really nice. http://www.neumann-kh-line.com/neumann-kh/home_en.nsf

I need closed head phone for work and home. I was looking at the Utrazone 750 pro, and the Beyerdynamic DT770. Also I have a NuForce D2 at work and wonder if a DT770 600 ohm can be driven by it.

How would a NuForce d2 be at driving a 250, or 600 ohm DT770?  Why the 600 ohm model, is it better if driven properly?

Has anyone listened to the Utrasone Pro 650, or 750, and the Beyerdyanmic DT770? What was your opinion?
