I've had the multi-bit and it is good for the price-point so would recommend that. Having said that - you will quickly find the itch to upgrade.
I was going to say something similar. could you stretch the budget to a Lyr3? Sometimes Schiit has refurbished/B-stock for sale at substantially reduced prices, and I think the Lyr might be a more evenly matched playmate for those fine ’phones.
