Sta 10 with TDSS experiences ??
« on: 16 May 2017, 01:47 am »
hello everyone. To give a bit of background first; i very recently decided to try out  Nu-prime for the first time. I purchased a pair of Sta 9's to run in mono with my Rogue 99 super magnum preamp . Ive been extremely impressed with this set up. Ive since decided to move up the line with the Sta 10. Now; what i would like anyone to comment on is whether this TDSS upgrade from coyote audio is worth the expense for the Sta 10. As i have read so many of the threads here, I'm really in a flux as to first whether i will be upgrading with the Sta 10 from dual mono Sta 9 and if so , second, then would the TDSS upgrade also be worth it? I've have NOT made the purchase of the Sta 10 pending some comments from you all , the nu-prime experts. Any comments would, I'm sure , be very helpful in my decision making

I can't speak to the TDSS upgrade - but I have experience with the 9's in mono. There's something to be said to the effortless about of power they put out. They laugh at impedance loads. I think it might help if the group knows how demanding your speakers are. John Casler also has extensive experience with NuPrime - he loves the product. I'm going to follow closely - I'm looking forward, as you, to learning what the group has to say!

Thank you for the comment.
The speakers i am using with the Sta 9's are Monitor Audio GX 300.

I've owned the ST-10 for well over a year and it is used every day.  It is a great amp just as it is designed and sold and I would leave it that way.  I also own the IDA-8 which is voice similarly to the ST-9 and to me I much prefer the neutral palate of the ST-10.

There are some very detailed threads on the circuitry of the amps and how they affect the sound between them. When you get to the 9 and 10, you've got some really great amps. Both will work well with your speaker. More power tends to give more headroom and a sense of effortlessness... That said your speaker is very efficient and should sound great with either. It really comes down to your personal preference at this point, I believe.


I look forward to more remarks from the forum.

Well, my ST-10 is paired to an awesome Don Sachs 6SN7 Tube preamp that push 83.5dB speakers. I really love how wonderful my music sounds.

I have played with the idea of getting the TDSS upgrade. I have chatted with TDSS Bob about it, but I have not pulled the trigger. I'll likely spend the money on Don's new KT-88 amp, so I can have two amps to choose between.

Just my two cents.

I am familiar with all the threads about the sound of the different Nuprime amps as well as John's preferences with the speakers in his stable.  So as you said it will come down to personal preference as to which sound profile the OP is comfortable with.  As a general rule Monitor Audio speakers that are most popular and sold most often have a tendency to be somewhat forward.  Having never heard a VMPS or Evoke speaker I don't know except from testimonials which side of neutral they fall on but I am not surprised the ST-9 is a match.  If the OP's upper end MA's are voiced similarly then the ST-9's may be a better match though not the better amp. Regardless I would not send it off to a "modder" without listening to it as the designers intended.

I think you are on the right track.  I have looked at Don's website more times than I can count and would love to try one but I need at least one pair of XLR inputs and outputs plus as they use a similar circuit and the same tubes I don't know how much different his preamp would sound from my Modwright.

Soundwise, the tweeter on the Evoke and top VMPS models is very similar to yours. As you know the sound is very open, spacious and true to the music. Your speaker also has a pair of mid bass drivers that are better at bass resolution than a single larger driver as a rule of thumb. So, based on that - I think you must have a wonderful synergy going on with your system. It's something I would enjoy listening to for sure.

I had my Dac10H and ST-10 modded by TDSS, and it was a very worthwhile improvement in depth, clarity and dimensionality of the presentation, and I'd happily do it again. Considering the reasonable prices of both the components and the upgrades, I see it as a package deal, with the result being a super bargain on excellent sounding, well designed gear. Since having it done a couple of years ago I've not even thought about changing them. They really are quite sonically invisible, showing everything in the system except themselves.
Good luck!

But you listened to it as is first which is what I am suggesting.

First off i would like to thank everyone for their comments thus far.
It seems to be a consensus so far that the Sta 10 is the more resolving amplifier versus the dual mono Sta 9's. However ; Jack has made a valid point; which has been my concern from the start.  The Dual mono Sta 9 combo may be a better match for my preamp/ speaker combo and i may have just gotten Lucky. To be clear , i did come into class D amplification fairly blind ; however, i did do my research. Rogue audio preamps do very well with class D (as told to me from Rogue), and Monitor audio uses Cyrus electronics for voicing. My history with monitor audio goes back to 1980 when i bought my first pair of MA r452 speakers in England. Over the next 36 years I've tried a few other brands (to try something different ), but i continue to come back to monitor audio. The reason i bring this up is due to this idea that monitor audio speakers are Forward or Bright... Nothing could be further from the TRUTH. The REAL problem that people have, is that they don't take the time to position their Ma's properly. i will concede that with the ribbon tweeter they are Very sensitive to positioning and source material.
Regarding the TDSS mod ; it seems that you guys seem to know of someone that i am not privy to. All i have found is this coyote audio group, of whom DO NOT ever answer the phone. Am i contacting the Wrong group??? Please inform me so that i may investigate further.
