Musical Fidelity NuVista 800

Jul 19, 2022 by Anonymous
Item Repaired/upgraded: Level 2 upgrade 

Upgrade done in an extremely professional manner. All Capacitors replaced op-amps internal cabling and speaker binding posts replaced.

The first thing I noticed was that the sound is so much smoother; sounding much more like a single ended amplifier.
The smoother sound is not at the expense of information; far from it.

I can now hear when woodblock percussion is being used; the structure of the sound is quite clear.

When listening to solo male singers, there used to be an artificial zing associated with the male voice. Now the voice sounds natural as I would expect it to sound in a live performance without amplification.
Orff: Carmina Burana the dying swan is an example of this.
Imaging is great, and dynamics have improved. The Amp also seems to work better at a lower volume quite a surprise!
This amp now punches way above its weight a very relaxing detailed sound worth every penny.

A5 CD and A5CR pre

Item Repaired/upgraded: Upgraded 

John completed a Stage 2 upgrade on my A5 CR Pre, I was using a Croft Micro 25R pre, sounded good but presented a vague and inconsistent soundstage. John assured my that the upgraded pre would bring everything into focus.. he was SO right. Next stage was to upgrade my aging A5 CD to Stage 2, what a revelation. I also have an Akurate spec LP12 and am really not sure if I prefer listening to CD of Vinyl now. In all my years of upgrading and listening to music I have never ever said that. The A5 CD is now simply staggering. John's advice and guidance has been invaluable through my upgrade journey (he also did a Stage 2 to my 550k power amps a couple of years ago)
Costs have gone up, but the value far out weighs the money I have spend so I am a very happy man...

Musical Fidelity Fully Balanced Pre

Item Repaired/upgraded: A1 FB Pre 

You switch on the amp you've cherished for 11 years and after a moment it turns off and you have that sinking feeling. You take it to the local highly respected repairers and you are told that the main transformer has failed and they cannot get a replacement.
You then dredge from the back of your mind JS Audio and give John a call and with a reassurance born of experience John tells you he can fix and it can be upgraded as well.
So I've delayed writing this review for a month or so to let it settle in now that my Musical Fidelity A1 FB Pre is repaired and upgraded. All I can say is wow....
An example of the improvement is one particular piece where the singer is singing about a gypsy market previously I could hear there was the sounds of a market hiding in the mix, but now if I focus on the market I can hear what they are selling the clarity is so clear no mush. Doesn't stop there though
Bass more tuneful more texture more bounce.
Treble is sweeter
It's like every part of my system has been upgraded
so a big thank you to John, he is a magician.

Item Repaired/upgraded: Musical Fidelity A3CD, Quad 34, Quad 405-2 

If like me you are wanting the right person to repair your HiFi separates you have come to the right place, John is excellent. My Quad 405-2 amp went bang so I looked at Quad service reviews, they were a bit hit and miss. My Musical fidelity A3CD player was skipping so I searched for Musical Fidelity repair and found John with 100% 5 star reviews. I phoned John up and just talked about my requirements, there was no hard sell or pressure at all. I then decided to get John to fix the amp and CD player but also to do a stage 1 upgrade on my A3CD, Quad 34 control unit and Quad 405-2 amp. The amp had blown one of the mid/bass drive unit voice coils on my Spendor SP1 speakers and John recommended Wilmslow Audio who replaced the voice coils on both mid/bass units, recapped the crossovers and rewired the speakers with new binding posts. So, how does the system sound? In a word, unbelievable. Everything is richer, deeper and more detailed, it really is like having a brand new CD collection. On great recordings I feel like I'm in the room with the musicians, the sound is so life like. Thank you John for doing a brilliant job on my separates, the sound is high end, just as you said it would be!

Stage 3 - Is there no limit?

Item Repaired/upgraded: KW500 

So had to take my kW500 for a check as I had clumsily shorted an input terminal (with the volume still up!) Asked John if he could do the stage three upgrade which includes a new Alps pot and upgraded capacitors, well it just gets better and better!! The sound stage is even more defined, the separation is phenomenal. If you've got a kW500 then let John at it and be prepared for a very pleasing outcome! As ever Genius!!
