Entry Level Tube Integrated Amps

"Entry level"?

No such thing.

Maybe lower priced, or affordable.

One way to approach this, buy the best you can afford plus a little more - meaning save a little extra. Consider buying something you may not want to upgrade latter on, which gets expensive.

Rogue Audio, Prima Luna, Quick Silver, or Black Ice Audio.

If you really want a soundstage sound it is expensive..You Have to match your Tube Amp with Speakers and cables ,DAC ,USB Cable for Streaming,..

I started with Raven Audio Blackhawk and when you start buying Military tubes cost start to add up along with cost of Amp.

But from Raven Audio bought the speakers that were designed for the Amps purchased from them...

But tube amps when matched with speakers and cables are the most enjoyable and musical reward to your ears...But Costly..

I second Rogue Audio. I have the Cronus Magnum II and it is probably worth twice the price. Great base which can be missing in some lower end tube amps. Amazing mid and high end. Phono pre-amp is above average. Two other inputs make it quite flexible without adding extra items. As a bonus RA will add inputs to allow for external preamps so you can grow with this integrated amp into a power amp.

Speaker pairing is huge. I recommend a dealer who will let you bring your amp in to audition speakers at the shop. The RA CM has lots of base so you may find some speaker pairings to have too much for your taste.
