Ok, i tested the preferred series (penta) kt88 against the Electroharmonics kt88. I ran them for several hours and here is the conclusions i came to. They were extremely close in performance but i will be using the Penta tubes. There is an ever so slight roominess, ambience, stage presence, with the Pentas. I'm not sure i could pass a blind test, but that's the truth and the best i could do. I would like to hear from anyone who has tested these tubes against each other.

Default EH vs Penta test

I ran the Penta and EH tubes for hours and then i compared the sound. The tubes are very similar. Both have wide frequency range with clarity. I will be using the Penta tubes. The reason is that the Pentas seem have a very subtle quality i would describe as ambience, like a slight reverb or stage presence. Your results could certainly vary and i am not sure that i could pass a blind sound test. I would like to hear from you if you have tested these brands.

If i had endless funds i would test the more expensive tubes, but for now I'm done. Once again thanks to everyone who commented on this thread.
