Audible Illusions vs CJ preamps: sonic difference?

Its been awhile since I listened to a CJ Pre or AI-m3a. Many years ago a friend of mine and I brought his VAC amp
and CJ Pre to Advanced Audio on a Sunday afternoon in Tacoma and listened to the AI m3a with an Ayre amp and a Wadia CD player through a large pair of Genesis loudspeakers. We never switched the amps, just the Pre-amps. No contest. The AI m3a was breathtaking. Through the m3a, Aaron Neville's voice floated out of those speakers with such majestic elegant grace and 3D imaging that we just sat their hypnotized. The only negative with AI m3a is they are known to burn up tubes in a short span of time. If you were to pick up a used AI m3a I would highly recommend buying Psvane tubes since they have a very long burn life due to their heavy filaments and thick glass envelopes and the best place to buy the tubes from is Grant Fidelity who is the premier vendor for North America. Grant Fidelity has the tubes shipped directly from the Psvane warehouse in China to your home so they arrive very qucikly by air so you don't have to go through a long waiting period with other vendors who receive the tubes at their business location first in the States then to your home.

The only tubes that Audible Illusions recommends fully are the Sovtec 6922's or the Russian Military 6H23EB's. Most all other brands they recommend with reservation which will result in a shorter tube life. They do not recommend you to buy at all the China 6DJ8H, the Sylvania 6DJ8 or the Philips 69J8. The Psvane tubes as I mentioned, are built to the standards of tubes 50 years ago and tubes from that era would last an average of ten years or longer due to their heavy filaments and thicker envelopes resulting in a higher heat threshold.

OMG!!..inferior service and risk damage that may occur? How shocking!! Grant Fidelity is the only Premier Vendor listed on the Psvane's website for North America. And I'm certain since the order is placed via internet to the Factory in China, that Psvane will make certain their tubes are packaged well enough to ship safely. Besides, it would take a MAC truck to run over the wood box the tubes come in to damage them, since they are built like the heavy duty type of tubes were 50 years ago. Inferior service is a false accusation against Grant Fidelity. They have their own blog made up of many Audiophiles that are very pleased with their service. Grant will also price match any other vendor's prices as long as you provide a web link or a price sheet and can prove the vendor is an authorized dealer.
Attempting to damage Grant Fidelity as a company providing inferior service is a low blow to get members to buy from Trelja. Nice try "Sandbox".
