Which amp/preamp/integrated for GoldenEar Triton 5's

There are many potential answers here, but try auditioning an NAD C 375BEE. It is surprisingly refined, powerful (150 wpc), stable, poised, transparent, dimensional, you name it. The preamp section is very musical and throws a big sound stage. Its amp section is quite a step up from an old 545. The C375 BEE is at the top of your budget ($1500) but solves your preamp problem while dramatically updating your power section with a great dose of integrated synergy to boot. If that’s too much, try the NAD C 356BEE. Same basic signal path, a little over half the power (80wpc) and price ($799).

Given the age of your amp and the fact you have indicated an interest in an integrated amp, I think at your budget an integrated would be a wise choice. There are many in your price range to choose from, and, as I am not familiar with the Triton 5s and power requirements depend on speaker impedance, room size, and loudness preference, I am hesitant to make suggestion.  I agree with the NAD suggestion as one possible choice. Can you provide speaker specs, room size, and listening preference info?  

Thanks for all your responses. I had considered the NAD's, but was a bit put off by their so-so reviews on whathifi and the number of choices they offer. And auditioning will likely mean either a long drive, or a buy and test with the possibility of return (which is where I am with the Peachtree). Would you get the NAD's with the DAC included, or use an external?
Mesch, the Tritons are supposed to be relatively easy to drive, and are in a living room/dining/kitchen area that is 20x40. I listen to a wide range of music and find I do enjoy turning it up if it sounds good!
Any ideas on what the general complaint is with Peachtree products? I know they're not at big as someone like NAD, but they get great reviews from what I've seen. And so far, it sounds pretty good to my ears (but with nothing to compare to...)
Thanks again for your help.

 I have heard some triton models however not the 5s.  I thought then to be very good. And had heard they are easy to drive. I assume the 5s are totally passive, requiring power to woofers. 

Are you willing to buy used? If so, I have had great success using the AG  marketplace. Also, what are your sources?

I don't know what WhatHiFi's deal is, but their reviews seem to be all over the map and have me scratching my head, esp. their NAD C 375BEE review. Sometimes they seem to enjoy the role of iconoclast, trashing highly regarded products (e.g., this NAD and also the GoldenEar Aon 3).

Their sonic criticisms sound to me like they take the time for warmup, let alone burn-in for electronics and break-in for speakers. Their descriptions of the NAD and GoldenEar products sound like the generic shortcomings of cold fresh product--hazy midrange, lack of frequency extension, and loose bass--criticisms they had for both the NAD amp and the GoldenEar speakers.

I certainly wouldn't take their uncoroborrated review on anything. There are lots of positive reviews of the NAD C 375BEE.

Notice both these reviews highlight the NAD's clear-yet-musical presentation and clean, tight bass, the very areas WhatHiFi considered weaknesses. I have heard the C 375BEE driving Magneplanar 1.7s (bought a pair) and GoldenEar Triton 7s.
