Integrated Amplifier balanced


I need some help in buying a Solid-state integrated amp. All my music is coming from a DAC (Slim Devices Transporter). The requirements are:

0. The best possible music within my budget (I listen to classical and vocal music).
1. Must support balanced inputs.
2. Dual voltage (110/220).
3. Under $3,000 used or new.
4. Solid build.

Bonus
1. Headphone output.

Greatly appreciate any advice.

How many pairs of balanced input? What else is in the chain (dac, speakers, etc)? There are a lot of options so this will help narrow it down a little.
All my music is on my computer (FLAC). I am looking at the Slim Transporter as my DAC. This is my entire chain! I need to get an amp and speakers.

I need one pair of balanced inputs. If the amp has a pre-amp balanced out, I might hook-up a headphone amp (Headroom) unless the amp supports headphone output.

Thanks for your help.
Is that budget just for the integrated, or the whole system? I would say that you may want to budget for a good DAC, since you can definitely improve over the Slim's DAC. One route may be to get a DAC with volume control like the Bel Canto e.One DAC3 and then get an amp and use the DAC as a preamp. I know someone who does this with a Pass 250.5 and likes it very much (although maybe still misses a preamp).

I have the Pass and love it. I don't know what they go for used, but I would guess over 3,000. I would think a YBA Passion Integre 300 would be a good route, or the Plinius 9200, both of which are very beautiful sounding amps, and both of which hold up well for resale (also match your criteria above).

I would maybe suggest pinning down your speakers first, because if you're going to buy and sell until you get the right thing, speakers are a drag to do that with; however, amps are pretty easy. You could also get a 2000 and under integreated and get a DAC that will perform better than the squeeze, unless you're going with a modded unit.
