Marantz 94 mark 2
« on: November 25, 2017, 01:50:22 AM »
Ian was over a few days ago with his full house modified Marantz 94 Mark2. He has spent many years perfecting it to this level. In its present state it is just brilliant and yes it has no valves. Its the only DAC that has been through this door that went neck and neck with my killerDac, it was very clean clear and noise free (one of his aims) Black indeed around the notes and they appeared to come from empty space. The sound stage is not as big and it does not have quite the bloom as the KillerDac, but is very similar in timbre and texture as mine. It has none of the slow plodding nature of standard Marantz 94s. It is relaxed, natural, smooth, and has presents, with a solid image focus, yum its nice. Shows you can build brilliant from just good. But before you run out and buy a Marantz 94 remember he has spent many years tuning this machine and he knows how to get all the hard to find esoteric capacitors and resistors, and most are not commercially available. Anyway i will not rave on any more, but hopefully he can come to this page and explain how it works. The pictures do not show the full story, because underneath there is a compartment stuffed with more toys. I really could live with this Marantz because it makes Music, They should have built them like this in the first place.

Hi Steve and Ian :)
Yes indeed it would be great hearing a blow by blow account of the upgrade path Ian has traveled in order to be able to be praised by SG!!!  It must have a couple of great sounding TDA chips inside it then.  What other equipment is the CD spinner being used with??

For something with OP-amps in the output chain it does not always mean it's bad............I recently put some dexa discrites in place of some OP-amps and was shocked at how much better it performed all round. I tired to avoid the more usual Burson's etc.

It is easy to spot  a lot of the changes implemented, the changed dac decoupling caps, the obvious clock board and the diode replacements.  I remember those original POOGE articles and that couple of hundred page Marantz CD65 upgrades on the  DIY hifi site.

I would love for Ian to describe the process and give a guide to the uplift various stages took on.  This website could do with more helpful information and it will bring increased readership I feel.  ;D ;D ;D ;D
We all like different things so lets all agree to disagree and if any common ground is found then worship it.  Mine is the KD hence being present on this forum.

Hi guys . I am travelling back home to Newcastle  at the moment. Rest assured  I will    post a detailed account  of  my  experiences  with  the Marantz cd 94 mk 2 as well as  other equipment  upgrades.
    One thing I will say now is that it is a holistic approach rather than using a super  TDA1541  double crown chip for example .  You need to reduce noise in every circuit  because its all connected .
  In digital ,  added noise means jitter . Capacitor quality  both in Electrolytic  and   film bypasses are critical to take things to the next level . Attention to clock power supply is critical as well as  the decoupling caps around the TDA1541  ( super sensitive )  .
     Thanks again to Steve  and Jen for being so welcoming   .It was an absolute  pleasure  to spend  quality  audio time   at their home .
