Jolida Fusion 3502. It hopefully will arrive tomorrow if FedEx cooperates. Could be fun.

Jolida Fusion 3502S Integrated Tube Amp

Combining the best of the JD302CRC and JD502CRC designs, Jolida dramatically elevates audio performance in the Fusion 3502S. With a flick of a switch, you can set this integrated to operate with 6550, KT88, KT120, KT150, or EL34 vacuum tubes. The EZ-bias circuit is completely redesigned to deliver a bandwidth of 8Hz—130kHz. Fusion 3502S also includes ESA clarity coupling caps, high-speed diodes, and DC voltage to the preamplifier tubes, improvements that lower the noise floor and increase frequency, linearity, air, and dimensionality. And let's not forget the sound. The moment you hear it, you'll know this integrated amp's clear, smooth, and three-dimensional signature is the kind only gleaned from tubes. All you need is to pick black or silver, and the tubes of your choice!

Very nice. Let us know how it sounds. I use a Jolida JD9 phono preamp in my system and I think Jolida offers great bang for your buck.

It arrived yesterday. Looks great. It's still breaking in. The first night it was a little tight, constricted and harsh. Now, it's a different story. It's opening up and smoothing out and sweetening up. I am totally amazed at the quality of the sound. It's wonderful. Bass is tremendous and surprising. I am sure after several hundred hours it will be stellar.

Update:

This Jolida Fusion 3502 is simply outstanding. The first night it was a little harsh like some new gear sometimes sounds. Now it is opening up beautifully, surprising amount of bass with 3D and depth. Lots of air around voices and instruments. This integrated is a knock out home run. If you want an inexpensive tube amp that can play so much higher than its price would suggest, run and get one. Mine is going nowhere. Now I am even thinking about the new Jolida Luxor VTM 100 monoblock tube amps coming next year.
