I traded my Magnum Dynalab 807t Internet Radio Tuner for their top of the line 809t Internet Radio Tuner. The 809t unit 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. They improved the DAC to boast all incoming signals to 24-bit/192kHz. Bases on my conversation with Magnum Dynalab, I also had them install Teflon capacitors to improve the sound quality.
I immediately noticed an improved sound coming from my 809t over the 807t and was thrilled. There was more detail, the bass was better, it was clearer and the overall sound quality was much improved over the 807t. I like the 809t very much and highly recommended it.
My 809t Internet tuner is connected to my Luxman L-590ax integrated class A amplifier driving my Sonus Faber Auditor M Speakers in my living room. The 809t tuner is connected to the Luxman integrated amplifier using Harmonic Technology Magic Link Two cables (XLR). My other music source is the Ayre CX-7eMP CD Player using Harmonic Technology Magic Link Two balanced cables (XLR). I am using Synergistic Research TESLA Quad Speaker Cables.
My Magnum Dynalab 809t tuner is a great sounding tuner. Once of the many advantages of the 809t is the selection of music sources. One of my favorites is listening to Calm Radio. They offer 100+ channels of different musical tracks (see www.calmradio.com). You can listen at 64k at no charge including commercials or pay a $60 yearly fee (I did) and listen at 192k with no commercials. Linn Classical, Radio Swiss Jazz and Radio Paradise are also excellent free stations.
Over the last several weeks, I am have been receiving an increasing amount of re-connection error messages when listening to music. I discovered that others were having similar problems using the Cisco Linksys E4200V2 router (my router) on their computer. It seems the Cisco Linksys maximum transmission unit (MTU) Auto 1500 setting causes re-connection issues. Cisco Linksys Customer Service said to change the MTU 1500 setting to manual at 1392. As instructed, I also changed the channel width to 20MHz and the channel to 9 - 2.452GHz. Since I made these changes, the re-connection problems have gone away.
I am using the Neutrik NADITBNC-F AES/EBU Transformer to convert my Ayre CX-7eMP CD player XLR 110 ohm output to the 809t's COAX 75 ohms input. I am using the DH Labs Silver Sonic D-75 digital cable to go from the Neutrik transformer to my 809t (BNC to RCA). I have done limited testing but it seems going thru the 809t's DAC sounds slightly better than the Ayre.
A friend heard my system last week and agreed the 809t sounded very good.
