@delmatae I do not know much about that amp, but you may want to consider a sub to relieve some of the bass if that amp does not have an abundance of umphf.
Even though most everyone in this thread is rating the Vandy, it would be good to have a listen/demo, as the people rating the Vandy high, are somewhat biased. (Myself included)
In all probability it is the best choice. But I am not 100% convinced that the Treo would be better than a 2C +sub (at a fixed budget). I think it would be… but I would be calling a dealer.
If you had gotten the 2C back in 88, then I would be telling you to get 1 or 2 of the subs now.
The Treo with the sub should be a step up from a 2, which is very good. So you likely want to have some budget for a sub now or later, just in case the amp is not much of a bass slammer.
