Best Integrated for under $1000

Antique sound labs AQ1003 DT

A few years back, I compared several integrateds. Amongst them was the YBA Integre Alpha DT. It was very nice.

However, to my ears, liked the Audio Analogue Puccini SE better. It was slightly lushly colored in the mid's, but it was OH so musical, more so than the YBA, and 2 other amps (2.5-4 times the price!). The SE is the way to go, with dual transformers and more dynamic power. It also has a built-in phono section, pretty good.

The new version comes with remote, though it may be harder to find used. Still, a dealer may be willing to deal on a new or demo unit, it floats around the $1100 to $1200 list I believe.

Lots of luck.

Audio Aero Prima mkI. Hybrid int with 3 inputs and a pre out. Had mine for a couple years with no complaints. Check the web site for details and purchase.

Musical Fidelity A300 150wpc.

I don't know about the Musical Fidelity piece mentioned previously at that price level. However, the older $5k integrated that MF made was simply world class, and the best I've ever heard!..and I've sold some mondo high end gear over the years...that thing was just gorgeous sounding!..migh be worth looking into as Cdc mentioned above.
However, I have dealt in the bargain little Jolida's at that price level or bellow used. For as little as $400-$1000 you can get a sonically superb little Jolida SJ502 or 801 integrated that sounds stellar with the right tubes and even some mod's! I think you'll love the sound with your Physic's! You might check into them. We used to have the jolida hooked up to Some Audio Physic's Tempo III's, and it was quite good. But, you might prefer SS with them, everyone is different.
Personally, I've always found the YBA's to be just "OK" stuff!..not much better than Classe, really. Infact, The Classe integrateds are probably better...but you might try and see. The Plinius is probably a good try for SS
