Jadis/Spendor system

I've owned Oval 9's in the past. A few years ago they were the hot wires. I say pick up a pair of the AU24's. Look for the best price--If they offer no help; you should be able to turn them for the same price'cept for maybe 10/15 in shipping.-- Another inexpensive sug.--If you have nada for conditioning; you might look for the Custom Power Block for a couple of hundred.The cord is fixed which saves a bit.---Again even this can be turned for whatever you paid.--- I think these are great things to try with a pseudo /kinda; money back thing. Least I forget-- have you done any tube changes??

No, they are the stock kt90 tubes.

Having lived with this amp for about five years, I think you need to look at a different pair of speakers.

Also, the amp sounds much better with either JJ KT88 or E34L tubes. Much sweeter and alive.

Personally, like with any amplifier, I have found some speakers to make it come alive, and others leave it to sleep. Along the way, I paired it with many different loudspeakers. The best combination was with my Coincident Digital Master/Troubass subwoofers, running either of the JJ tubes. It simply played the music exactly right, and the resolution, refinement, dynamics, and believability were wonderful. I have never before used the word "perfect" to describe anything audio, but the tonality was perfect. THE absolute best sound I have ever had.
