Best inexpensive integrated for PSB Gold speakers.

Well, going from 80 to 120 watts is not going to make much difference. As I recall, the PSBs are quite sensitive, so an 80-watt amp with plenty of headroom (a la NAD) should drive them pretty well, unless you've got a big room or a thing for ear-splitting volumes. I haven't scoped this market, but I'd guess that an integrated that's both inexpensive and substantially more powerful than what you've got will be hard to come by.

Patriot, the PSB's are quite insensitive, and will require a powerful amp in order to open up. They feature a difficult 4 ohm load(dipping even lower in some regions), with a phase angle equally as daunting.

While PSB lists their sensitivity as something like 90 dB/2.83 V, I always argued this. Measurement by Stereophile's John Atkinson confirmed my suspicions. The values he observed were closer to 83 dB/2.83 V. With the aforementioned impedence/phase angle.

I have personally spent a lot of time with these speakers. Coupled with electronics by Sony, Adcom, and Carver. Of the myriad amps I mated to these speakers, I only saw the true beauty of this speaker with the now defunct Carver Lightstar. Everything else, including the behemoth Adcoms never allowed this speaker to come to life.

In those times when I drove these speakers by the Lightstar, it was absolute magic. No, they aren't perfect. No speaker is. They can be a bit bright, and the sound is not the most refined. But, at their price, with the right amplification, you have a wonderful speaker. Dynamic, deep, fast, and open. In fact, at times, I was even awestruck. Build quality is very good, as are their looks/WAF. I would caution you to keep a keen eye on making sure the driver's bolts are tight. Rigorous exercise loosens them up faster than one might expect.

I would suggest that if these speakers are keepers(and they SHOULD be), please look into a Carver Lightstar or Sunfire power amplifier. Otherwise, you are selling yourself, and, especially, these speakers short. I cannot think of an integrated(and I am a huge fan of integrateds) which will do these speakers justice, so I am recommending you rethink your choice in amplification

Good luck!

Both Bomarc and Trelja offer good advice. To expand on Bomarc's comments, bear in mind that doubling the amplifier power only results in a 3db increase in SPL, which is not a major increase in volume. If 80 wpc isn't enough for your PSB Golds, you should be thinking in terms of a 300 wpc power amp. But power isn't the only issue: quality is the other factor. The PSB Golds are pretty damn good speakers, although they are inefficient (their published efficiency rating is incorrect), and they deserve to be powered by a high quality preamp/power amp combo.

A NAD 218THX will work well with those speakers if you are on a tight budget. You can use the 317 as a preamp.

I have been extremely impressed with the Nad 370. I am using the 370 to drive the new Audio Physic Virgo 3's ($5500) and have been astounded by this amp. I bought it to tide me over until the new Bel Canto eVo integrated comes out later this month ($3200). I have been using it with a modified 9000es with a lot of SACD's the resolution power and control of this amp is amazing. In the latest Stereophile the measurements show it at 178W per Channel at 8ohms. If you need more power you can biamp with the NAD 270 power amp giving you 300W per channel The 270 can be had for a street price of around $500 and Qaudio.com has the 370 for $549 unbelievable.
For an inexpensive powerful integrated this is hands down the way to go ! This new Nad is so much better than the 317 and other previous Nad gear I have heard including pre-pow combos
