In the Thread: The FM Stereo and Multiplex MPX decoders
Post Subject: Multiplex decoders: T85++ vs. TU-1XPosted by Romy the Cat on: 7/22/2008
I mean to make this post with the observations for a number of weeks. The days are passing by and I hoped that I might get deeper to the bottom of it. Unfortunately I was not able to.
So, the Rohde & Schwarz EU-6201 is feeding a modified Yamaha T85 Multiplex decoder from one side. (There were other change in T85 – in the PS – they are not visible on the circuit above). From another side there is the TU-1X with own stock Multiplex decoder. Which one has better stereo? That question I asked myself many times trying to discard any other differences those FM setups have.
Well, the T85++ and TU-1X Multiplex decoders do produces a different stereo. Tonight the WCRB broadcasted my favorite Kalinnikov’s Symphony #1 with Jarvi leading Scottish National Orchestra (Chandos Records CHAN-8611). After the 100s times of listing this I was not able to help myself to hear it again in full Macondo's blume. Is anything might be more magnificent then VERY LOUD play of THAT first movement!!! Both Schwarz and Sansui were on (I never show down Schwarz – it is on all time) and I flipped the buttons on my preamps input…
Yes, I do detect the minute deference in stereo presentation but I honestly can’t say that one is better. They are different and each one then in own way good. The Schwarz-T85 has a very slightly more extended HF that makes the stereo imaging comparing not truly objective. However, I have no problems with ether of the stereo decoders…
Ok, I do admit that either T85’s or TU-1X’s are not the “intellectualy absurd” type of the stereo decoders - something to which I generally accustom in my audio solutions. Knowing me you should not doubt that the “intellectualy absurd” decoder will be coming. For now, I have to acknowledge that both T85’s and TU-1X’s MPX Decoders are very fine, different but very fine. It is highly possible that the “End of the Life” FM stereo decoder will not be better then what either T85’s or TU-1X’s decoders do cruelty. Well, perhaps there is no room for it in terms of sonic results… it is what I hope…
