After waiting some three years for my tires to wear out, installed some Goodyear Assurance tires and have found the road noise to be reduced significantly. The exact tire I bought can be found as:

Do ya'll think you can take a all wheel drive "luxury" car and start its price @30k and not remove or leave stuff off????
there is no insulation under the rear seat. So start there by installing either dynamat or at least carpet jute. Personally i would pull and the seats and carpet. Install full sheets of dynamat to the floors inside. Then reinstall everything and you will notice a huge differance in how quiet the car is afterwards. Want the doors to sound more luxurius when closing them and also reducing noise. Insall strips of dynamat to the inner metal of the outer door skins after pulling the door panels to access. Now drop the headliner and do the same. The added benifit is the car will stay cooler in summer and warmer in the winter if you use the foil faced dynamat and be so quiet youll swear your amost riding in a new xj without roof pops

Amazon are offering Free Shipping on this product - just now. (but maybe not for international) However, now we have a product named, can search and obtain its working properties... to then find similar (local) product.
I've not been involved in the Auto building industry for over 30 Years now (retired) but I still recall sound-proofing Caterpillar D9 bulldozer Cabs... as used for tree clearing out in the Bush. Then, we used a 1" thick HD foam that had a 16th lead sheet membrane sandwiched in centre - effectively attenuating 120 dB engine noise.

I'm sure the advocats of soundproffing have their merits and probably a worthwhille exercise if the noise is that bad.
Personally, I think tyres are a bigger issue.
I ran my A6 as quiet as a mouse on either Bridgestones or Continentals......recently moved up from 17's - 19's and on Khumo Ecstas and after a few thousand miles I have issues.
As someone above posted, it sounded to all the world like a wheel bearing has gone. I had this checked by a tyre specialist AND Audi who both said no wheel bearing issues.
It looks to be an issue with the tyres. Although the tread is fine and well within legal limits with around 4 mm left, when rubbed one way it is smooooth, try rubbing the tyre the opposite way and its almost razor sharp........the condition is known as sawtoothing I believe.
The wheel bearing type noise has gradually gotten worse......I fear I'll have to live with it until I get new tyres!
At £1000 a set its kinda hard to justify a new set to replace a half worn set though so I may be stuck with this a little longer.

My tires are pretty quiet but I'm also interested in making the cabin more so. Please keep this topic alive if you end up doing something. Seems like there's a few of us thinking the same thing

HI Guys,
I had one of the first XJ6 series 1. cars. I think it was a 1969 or 1970. The ride in that car was fantastic. It was smooth, very little to no road noise and so quiet I could often hear the clock ticking on the dash. Apart from the fact that is was a Daimler model which came with extra underlining under the carpets I think the tyres had a lot to do with the ride. In 1968 when the XJ6 was first released they came with 15" Dunlop Aquajets which from memory were especially made for Jaguar for the XJ6 and were a textile radial not a steel belt radial. The Aquajets gave me an extremely comfortable quiet ride and I followed the recommended tyre pressures in the book which were 26Psi in the front and 28Psi in the rear.
Now nearly forty years later I have a 1996 Jaguar XJ6 X300 which I purchased recently and it came with the standard mag rims which are 16" and fitted with Michelin on the rear and Good year Assurance on the front. From memory, although this X300 is much more up to date and handles better all around I am not convinced that it rides more comfortable than my 1969/70 early XJ6. If your priority is comfort like me, and a Jaguar is the closest you can get to a Rolls Royce or Bentley in smooth quiet ride then one might find that wheel size and tyres are worth studying, as the modern trend to large wheels and very low profile tyres is slowly destroying the soft comfortable ride of our modern cars. We are being encouraged by the new fashion car industry to buy the latest style which is more about speed and image than real Luxury. The Brand name and the look alike has become the main alluring bait to the modern consumer. And then there is likes of top gear, who have the expensive car buyers obsessed with unusable speed and handling, to the comparison of "buying as speed boat for a swimming pool" I have to drive down my street at 50K past the school at 40K along the main road at 60K, move away behind a fast car slowly at traffic lights, because he or she does not want to burn too much fuel and then I finally arrive at a freeway backed up with traffic and if lucky achieve short bursts of 100Kph to the max of 110Kph as no one wants to get out of my way or anyone else's for that matter. When there is a break you would think they are driving the slowest car on the road. Now here is the bottom line. I am 69 and I am not a lead foot. I don't even care for driving much at all and I hate speed. I have no desire to go sideways around a corner, even on a race track, but when I am driving and sitting at the front of the traffic lights, I like to get up to the speed limit in a few seconds so that the cars behind me can get away faster if they wish, but I can do that easily in my wife's Toyota Corolla and often leave the super elite, needy modern car lover behind standing. Now there is something to think about, from an old car buff who has owned and paid a lot of attention to the car industry since his very young school days which was located in the heart of the city's main car distributors in England. Jaguar, Triumph, Sunbeam, Morris/Austin Vauxhall, Rolls Royce/Bentley and Rover.
