Kenwood 3020 Upgrade
Ver pleased indeed, it just seems to keep on improving. Biggest difference it there is much more space now. All instruments have more of their own space now, this is so noticeable on tracks where there is a lot happening. 

It's just great to be able to go through all my music again and see what it sounds like now :-)  What amazed us was when I put on the 12" vinyl of America For Beginners by Latin Quarter - that is just an amazingly well produced track with a fantastic sound whatever you play it on, so I was more concerned with listening for any losses rather than improvements, but there really was an improvement in the sound and we could hear details that we had not noticed before - I wasn't expecting that!

Musical Fidelity Pre 3A
I recently purchased a twenty nine year old Musical Fidelity Pre 3A 
with separate power supply of unknown origin from ebay and sent it to 
Lee from Redhill Audio for renovation. I was previously using a 
Tidsbury Audio passive preamp-a steal at £130 but not really in keeping 
with the rest of my system which comprises an old but heavily modified 
Linn LP12 with DC motor from OL fitted with a Rega RB300 rewired and 
polished by Johnny 7 at Audio Origami and an Ortofon 2M Black. This 
feeds a Musical Fidelity XLPS V3 phono stage whilst CD comprises a 
Cambridge CXC transport with Audiolab Q DAC. Along with the 
aforementioned preamp is an Audiolab MPWR feeding Spendor A5R speakers.

First impressions are extremely positive and immediately noticeable is 
the complete absence of hum from the phono input which was previously a 
persistent bugbear. The improvements wrought by Lee's modifications are 
in no way subtle-it is immediately obvious that the soundstage has 
opened up,spreading well beyond the plane of the speakers, whilst bass 
is noticeably better timed and with a solidity previously lacking. 
Similarly, detail has markedly improved and even with extremely 
familiar material, new aspects of the music have been conveyed for the 
first time. As Lee remarked in one of our phone conversations, these 
modifications will take time to bed in, just like speaker drive units 
and cartridges and I look forward to hearing Lee's work at it's best in 
a couple of months!

Lee has kept in touch with me throughout the course of the work and 
even gone to the extent of phoning me to check I was happy with his 
modifications. I can recommend him whole heartedly and feel sure that 
despite the cost involved even vintage gear such as the preamp I 
described can sound absolutely fantastic and represents great value for 
money. For many cash strapped audiophiles( such as me!) I think this is 
the way to go!

Thanks again, Lee!"

Marantz CD 94 MK2 / Quintessence Voltage Regulator
Hi Lee,
Just to let you know that the repairs to the Marantz CD94 are working fine and the Quintessence +5v Regulator upgrade has made an amazing difference. There is much more detail and it is far more open now. It seems to have brought out the best in the various previous "upgrades" you have done for me :-)
First chance I get I will let you have my Amplifier to go through as you suggested...!
All the very best

Arcam Alpha 9 CD Player Power Supply Repair
Doing business with Red Hill Audio is pretty easy! My CD player had suffered the hum problem, from decaying electrolytics in the power supply, and it was simply unlistenable to. I've had to change capacitors in my PC Monitors from about the same era, it is a common problem. The CD player is a four layer plated through pcb though and I wasn't confident my manual desoldering gun was up to the job. Red Hill repaired and upgraded the power supply and it performs beautifully again. My set up brings a smile to my face, I hadn't realised how much I missed it! The packaging on the return was excellent too! Highly recommended.

Audiolab 8000a Upgrade - Stage 2 + Stage 2 Phono Stage Upgrade
Hi Lee,
I must say, the amplifier sounds really lush, the knobs work without distortion, the sound is to die for! The bass has improved as well as the mids and highs. My system now plays music! Wow! I can't wait to her what it sounds like after I get to the 300 hour mark!
Lee, I can't thank you enough! Thank you very much for this!
With Kind regards,

Quad 66 CD & Preamp Upgrades (Stage 2)
Hi Lee,
Having given the CD player & preamp a thorough burning in over the weekend, with your interconnect between both, I have just had a revisit to see (hear) how it was going. Wow! I am both delighted and overwhelmed at how it sounds now. Right across the frequency range, everything is so much better - tighter, deeper base, sweeter high frequencies, and a more open midrange. Added to that, I am hearing subtle details that I hadn't before. I am very very impressed. 
    Also, I have done a direct comparison between your 1TP-S, and rather more expensive interconnects that I have. These were connected from the CD player directly to my headphone amp, so that nothing else would have any influence on the sound. I much preferred it to one, and it was at least on a par with the other, which is twice the price. So very well done for producing a high quality interconnect at such a price.
    As you can probably tell, I am absolutely delighted with what I am listening to now.
Kind regards, and many thanks.

Pink Triangle Cardinal, Da Capo, PIP2

I have been seduced by the transconductance amplifiers (PIP, Integrale) and DACs (da Capo, Litaural) from Pink Triangle designers. These produce signals which bring out the best in certain British speakers. Despite 20 years since the loss of this company these high end products still have a distinctive sound. With the unique skilled and resourceful support from Lee at Red Hill Audio it is possible to extend equipment life and update to modern power supplies and components. My friends and family and constantly shocked by the musicality and detailed sound. A great source of pleasure!

1TP SPS Interconnects

Hi Lee.

One thing I did do, was to swap my Chord Chameleon (not the warmest of interconnects) from CD to pre-amp, with your interconnect. Now that I was immediately impressed with. I lost none of the detail of the Chord, but got a much warmer, richer sound. I'm assuming that like the components you've installed, this will also benefit from some burning in time. So very well done for producing a quality interconnect at that price. Got a feeling that it is staying put where it is.

I should have got back to you sooner to say how pleased I am with the upgrade - my excuse is that I've been too busy enjoying it. Positive feedback now left on eBay.

Dear Lee, 
I’ve been meaning to drop you a quick email to say thank you once again for fixing the old Audiolab amp. It arrived safely, carefully packed, and it is sounding fantastic and the RCA connections are solid. Very happy indeed with the service, and would recommend you highly. Best wishes for the future.
With kind regards,

Quad 405 II Stage 1 Upgrade

I hooked the upgraded Quad 405 2 up to my home system for fun yesterday. I had no idea just how radical a part the amp plays in the chain! My problem now is that I want to upgrade everything. The clarity and subtlety of sound is remarkable. I'm stunned. It's made me think again about how we listen to music and how important it is to stay true to the integrity of the original recordings.It's about getting the full emotional impact. The timbres within orchestral music and depth of sound are no longer averaged up and presented as a kind of classical sponge. Vocal harmonies are presented as layers and not blocks. Dynamics are effortlessly observed and expressed with breezy ease. It is a completely different experience of listening. There is an artistry in your work Lee.

Arcam Alpha 9, 9p Amplifiers & 8SE CD Player Stage 2 Upgrade
Lee, just a quick note to say thank you for the work you carried out on my Arcam 9 / 9P amplifiers and 8SE CD player.  I'm only a few hours into listening to them but my CDs and vinyl LP's sound absolutely fantastic, there's a feeling of breadth and depth and accuracy to the music present now that wasn't there before - Arcam Alpha equipment had a reputation for over warmth, softness and flabbiness at times but that's certainly been dealt with.

I'm sure I would have had to spend many thousands of pounds to get a similar level of detail and precision if I was starting to build a system from scratch, instead you've breathed new life into my old equipment at a fraction of the cost.   

Really pleased with the outcome and I'm looking forward to more listening as the new electronics run in and hopefully improve the sound even further.    

Superb service and communication throughout and I have no hesitation in recommending your services to anyone who may be looking to upgrade their vintage kit.

Marantz 2238 Service/Upgrade
Hi lee,

Just a quick note to say thanks for the work on the Marantz receiver.

It’s definitely sounding better (more clarity at all frequencies but the bass lines in particular certainly bounce along nicely).

Very happy with it, so thanks again.
