HD 598 with Bottlehead crack?

[leviathan]

Hi,
I have been looking at my first tube amp and I keep seeing the crack being recommended. I currently use hd598s and plan on upgrading to hd650s or something along those lines, maybe 7 or 8 months down the line. Will the 598s work until then or should I not use them with this amp?

I think these are 50 ohm impoedance headphones, they will work but not optimally IMO and based on the Crack being an OTL amp and designed for higher imnpedance headphones, like 300/600 ohms.
