VTL's and KT88's?

I've got a pair of VTL 300 deluxe mono blocks and currently use Gold Lion KT-88's. In my system, with my equipment they are great. They roll of the high's silky smooth and oh what a sweet mid range. They don't have the tight bass like the 6550's but I think it just my speakers.

I tried the Chinese KT 88-98's because of the cost. I really liked them but they were a unreliable. I cheap'ed out and didn't buy them from Kevin Deal. Oh well live and learn. I did go to Kevin for the Gold Lions and I've had no problem.

Good luck

I've got Gold Lion KT-88's in my ST-150 and I hear exactly what vegasears hears....superb.  Except with my Thiel 3.5's, the ST-150 even in triode mode handles the bass better than either the ST-85 or ARC D90b that I've used previously.  Not quite as defined as a transistor amp, completely realistic to the real thing.

The best sounding KT88 is the Shuguang WE-KT88 plus red base tubes.  They are 3 dimensional have tonal qualities in spades, but they will not stand up to the high plate voltages on the MB-450, or other VTL amps.
If you try a Chinese KT88, you will get flash over and early tube failures. So stick with the gold lion KT-88s, or if you want a touch warmer sound, try the Electro Harmonix KT88.

@johnss  That's exactly how the Shuguang K-88 performed for me back in 2009.  I only use GL KT-88's in my VTL 450MKII amps.  Thanks for the comments on the Electro Harmonix KT88's. It may be time for a change.
