The letter "t" in the Magnum Dynalab 807t means the unit has vacuum tubes in the audio stage. The 806t and the 807t have 2 6922 vacuum tubes and the 809t has 4 6922 vacuum tubes. See http://www.internetradiotuner.net/
My 807t Internet tuner is connected to my Ayre AX-7e integrated amplifier driving my Sonus Faber Auditor M Speakers in my living room. The music source is the Ayre CX-7eMP CD Player using Harmonic Technology Magic Link Two balanced cables (XLR). The 807t is connected to the Ayre AX-7e integrated using Harmonic Technology Magic Link Two cables (XLR). The Ayre AX-7e Integrated amp sounds much better running balanced inputs and not RCA inputs. Many reviewers have said this.
Yes, my Magnum Dynalab 807t Internet tuner sounds excellent. I had several friends over and we switched back and forth between CD's and the tuner. Everyone felt the tuner sounded excellent. However, when I heard the 809t has two power supplies, a newly designed audio stage with 4 6922 vacuum tubes, a 5.7 color touch screen, 3.5 touch screen remote and no capacitors after the gain stage of the tubes, I decided to upgrade. Magnum Dynalab also improved the DAC so that it boasts all incoming signals to 24-bit/192kHz.
These Internet tuners allow you to create and organize your favorite list of stations via an Internet Radio Portal website. This feature allows you to have a full list of the stations you listen to regularly on one page instead of having to search each time. Some stations come in sounding better than other stations. I try to select Internet stations that are using 128k or higher. Stations using lower numbers (such as 48k, 64k, etc) do not sound as good.
As per Magnum Dynalab instructions, I setup the Frontier Silicon radio portal for this capability. It is free and very easy to use. The portal provides an excellent search capability to help you identify the Internet stations you want to listen to. You build your list on the computer and select the stations you want to listen to on the Internet tuner. This is an excellent feature and makes the Internet radio selection process much easier. New stations can be easily added or deleted using the Frontier Silicon radio portal. See

Bgordonr: As you suggested above, I added 3 stations from Radio Swiss Jazz to the Frontier Silicon radio portal to my Jazz category (took less than one minute). Two of these stations are Internet stations only. I listened briefly and they sound terrific. Thanks for the tip.
I hope I answered your questions. Please not, please let me know.
