Any affordable intergrateds known for huge sound?

What does "affordable" mean? For $2000, you can get a used Plinius 8200 MKII. That will give you "huge sound!" Or, for less, a Plinius 8100 or 8150.

For the same money as the Plinius at $2k-$2500 you can get a MUCH MUCH MUCH(yes indeed MUCH!..) better sounding, world class even Musical Fidelity integrated that is absolutely gorgeous sounding! The piece at around $5k new is the best integrated I know of...and I've heard a lot of em.
For cheap, try the Jolida 502b tube piece.
Although, what speakers are you using?

I have enjoyed both of my Krell KAV 300i integrateds. They go for around 1100 used and through a variety of Sonus Faber speakers have done a fine job for me. With a Synergistiac Research power cable you can even kick it up a notch when you are ready to.

Jolida has a brand new integrated I heard last night with a pair of B&W N805's. Great sound. Fully tubed with 100 wpc and some really decent bass. $1695 brand new, but we all talk the salesman down at some point. The Plinius, from what I have heard is an excellent piece. Also the Krell I know is quite powerful and can throw a nice soundstage, atleast when I heard it.

Try Redgum, I also second the Plinius 8200mkII.
