NAD T777 AV Receiver Signature Upgrade

Hi Dave,

I am just now listening to my SE upgraded NAD T777 AV Receiver.

I am totally blown away with the clarity and details of the sound and the surprisingly tight deep bass that I have never heard from any of my previous systems!

I now totally understand that the signal has so many opportunities to be degraded and corrupted. What needs to be done is to keep the signal as pure as possible, the way it should be. I now hear what you speak about on the website.

So any part of the link from receptacle to speaker needs to pass signals from one to next without loosing. Any weak link will determine the quality of final output.

I will keep purchasing SE upgraded internally shielded gear from you to complete the entire system to pass only pure signals from start to finish. My Oppo player is next.

Thank you so much for the introduction to the REAL HiFi world.

NAD C356 BEE Integrated Amplifier with built-in DAC upgraded

Bang for Buck

One might say that there is nothing more depressing than an audiophile on a budget. That was true until The Upgrade Company came along. I had NAD C356 BEE Integrated Amplifier with built-in DAC upgraded. I researched the Upgrade Company and decided to take the plunge.

After living with the consequences of my decision, I can say that there is no way I’m sending this unit back under the "Buy Back Guarantee".

For under $2000.00 I have an integrated amp with a DAC whose sound is definitively quite stunning.

There’s no question that after the upgrade this is no longer a mid-fi amp. Without going into a string of positive adjectives the sound is simply fantastic and very enjoyable. I am especially enjoying orchestral music. David Schulte was most helpful and responsive throughout the process. Audio nirvana is now definitely possible on a budget.
