The peach tree would likely be the cheapest solution. The “Peachtree Audio i NOVA - Integrated Tube Amplifier with DAC” is the one you want. It’s discontinued, but there’s one one ebay for $595. Then you can roll 6922 variant tubes for whatever sound you want.
Another idea are the Vincent Audio Integrated amps. They are very nice and very smooth and very warm, but higher priced at 800-1000. And you still need a DAC with a streamer.
