Power Amp advice

I am looking for advice on a power amp to drive my Magnepan 1.7i's.  My source is my Cambridge Network player which I use to stream Tidal.  My preamp is Tube unit: Transcend 6SN7 Line Stage by Aric Audio.  My current amp is a Parasound HCA2200.  The Parasound has lately developed an annoying hum.  I was thinking of getting it repaired, but thought that now might be a good time to upgrade that 30 year old piece.

I was looking for advice on a good match for the preamp/speaker combination.  My budget is around $2,000.  I don't mind buying used.  I was thinking to go with tubes, but I fear that any tube amp with enough oomph to properly drive those Maggies would be well outside of my budget.

Discussions here are always thoughtful, so I am looking forward to what you folks have to share.

Thanks,
Mark

If your amp has a toroidal transformer that may be creating the hum. You could try checking the fastener(s) on the transformer.

I installed DC blockers in my earlier Innersound amps so that the transformer would quiet down. These can be made with a bridge rectifier and a couple of electrolytic capacitors. The newer Sanders amps use a fully potted toroid and have virtually no electro-mechanical hum.

By the way the Sanders Magtech should be more than up to the task of driving Maggies or just about any speaker. I have two with LMS (speaker management system) driving my Sanders electrostats. Best sound I've had in my 40+ years at this "hobby".

Good luck.
