You are quite welcome. I'm glad I could be of assistance.

Heh - that was a year ago I posted that, but I still use my Ultrasone Proline 750's regularly - as my main non-IEM headphones. Sound better and better with age.

Good to see you are still around, Peter!

I have been away from Head-fi for quite a while now. After several years of absence, I decided to pay back a visit to this wonderful site.

I am still using my Proline 750 as my main headphone and the sound it produces never ceases to amaze me. Although I have tried many other headphones which are highly regarded by many head-fiers, I must confess that I keep coming back to my Proline 750 with its amazingly addictive sound signature, which is simply pure, extremely accurate, body-quivering lows, and deeply immersing especially due to its S-Logic design (and, yes, S-Logic does work).

One thing I would like to emphasize when using the PL750 is that you MUST hook it up to a high-quality source. The rule of "Garbage In Garbage Out" applies exactly to the PL750 since they so accurately reproduce whatever sound is thrown to it, whether it be background noise or the person coughing behind the recording studio. As an example, my PL750 is usually hooked up to my Graham Slee Voyager headphone amp which is fed by my old trusty Nationite S:Flo2 (dual-mono design with 2 separate Wolfson WM8740 DAC chips per channel). With appropriate high-quality FLAC recordings, one can only be amazed at the music reproduction you get. And, by the way, always set your equalizer to "Flat" for proper sound reproduction or otherwise sound will be distorted.

Just wanted to add my humble but very honest opinion on the Proline 750 after having several years of extremely satisfying usage.

By the way, kudos to Peter for his continued support for the Proline 750, a definite real gem.

Thank you for your kind words, Worldman. I meant to write to you before but my attention was diverted. I also keep coming back to the Pro 750 for basically the same reason as you. As a matter of fact, I am listening to them right now. Until very recently it has been a number of years since I have been on Head-Fi. Without mentioning any names so as to not annoy others who prefer headphones other than the Pro 750, I have experienced certain other headphones and while some had excellent sound, I have yet to hear one that I preferred to the Pro 750. One of the important aspects in my decisions has to do with the Ultrasone sound stage which, because of the S-Logic effect, I really enjoy. While certain other headphones have a wide sound stage or an interesting "blanket" placement of the various sounds, the overall effect is not the same and, in my opinion, not as pleasing, involving and interesting.
The next headphone I want to hear is the Ultrasone Signature Pro. Have you heard it and do you have any comments about it? If anyone has heard the Signature Pro and if you generally like the Ultrasone sound stage, I would like to read your comments.
Thanks again, Worldman. I look forward to reading your next post.
