NAD 304 - Best SS amp ever?


I'm being silly, of course, but my experience with this integrated amp has been really baffling. I'll give a brief historical outline

I. Bought one in 1994 on the strength of Corey Greenberg's utterly excited "this is real high end audio for $300!" review in Stereophile (btw, this review isn't anywhere online that I can find). After owing it for a few days, the skeptical retailer asked me if it sounded as "glorious" touted? Well, powering my lil' Dahlquist DQ-16s, the answer was YES!

II. In 1995, something went wrong and I needed a repair. That was the old "green circuit board" version. Borrowed a Quad Amp and Preamp...maybe a 405 with matching preamp? Sounded big and warm.

III. Got the NAD 304 back with new Blue circuit board. Sounded way bigger, more dynamic, and clearer than the Quad set-up. Loved it! had to sell it off later that year to help with some debt.

IV. Bought one in 2008 for $175. I'm using it to power Triangle Zerius 202s. I know, not the first combo you'd imagine, right? Sounds very clean and not lacking tonally, but now I'm looking for more dimensionality and palpable presence. I have tried using more powerful NAD amps, a high-powered Adcom, and I'm currently trying a Parasound HCA-750A. Everything sounds...ordinary. To be fair, the Parasound has warmed up and is starting to sound pretty good, but it doesn't exactly blow the 304 away.

Am I going to going to have to look at much more expensive gear? Tubes, maybe? Some of the amps I've tried have been very affordable, but the Quad and the Adcom were kind of ridiculously high-priced IMO, and the 304 was hands-down the winner in those shootouts.

Has anyone else had a similar experience - and if so, what did you finally choose upgrade with?

To rephrase the question,

Have you ever upgraded from an NAD 304? If so, what was your upgrade path?
Right on, Dred, thanks for sharing your experience!

The 304 is one of those products that really merited its excellent Stereophile review.

I wanted to update my findings in that, after further listening, the Parasound HCA750A *is* an upgrade in image solidity and deep bass. It's a more powerful sounding amp for sure. I still like the 304 though.

My next attempt at an "upgrade" will likely be an upgraded B&K ST-202. Dred, please keep me updated with your hybrid integrated experience.

Also, are you using the stock jumpers? I am using 20" of Kimber PBJ between the Pre and Amp sections.

This is so fun!
You know, I'm using the 304 as a pre-amp now. After a few months with my Triangles, I am hearing the 304's limitations... namely rolled off extreme highs and lows. Shortly after writing this, I spent some serious listening time with the Parasound amp and realized that it was pretty great, if a little "hard" sounding in my system.

I'm curious about the 315Bee and the 325Bee as well. I assumed they would be only marginal improvements, but a remote control would be awesome.

I'm curious about the B&K ST-140 (the older, 70WPC one), the ST-120, and the newest Parasound Zamp. I've also heard some great things about the Onkyo A9555 Class D integrated.

Finally, I take no offense at anyone's opinions about the 304 (or any of my gear) for that matter. Taste is taste, and good is good. Cheers!
My sources are: SONY DVP-NS715P as a CD / DVD player, Technics SL1200 with KAB Fluid damper and Cardas arm rewire w/several cartridges :)

I replaced the jumpers with 20" of Kimber PBJ which is different, though not an obvious improvement.

I can also say that the phono stage on the 304 is not quite as robust sounding as the one on the 7100 (at twice the retail cost)... which, while I'm at it, has anyone here used the Bellari phono stage? $250 and Stereophile Class B rating from Michael Fremer... is it really that good? I'm skeptical.

I miss Lonnie Brownell's reviews. I found that his and, previously, Corey Greenberg's reviews were aligned with my own tastes more than anyone. I also have a soft spot for Sam Tellig.. but I'm way off topic here. :)

I'm unemployed, so no new gear for me for awhile. Anyone need a recording engineer?

An update: My stalwart 304 has developed some problems - flakiness/fuzzyness/intermittent cutting out in the right channel. I understand capacitors and solder joints are usually to blame, so I'm going to have it repaired.

In its stead, I'm using my new Trends TA-10.1, touted as 6 Watts of giant-killing, audiophile magic.

So far, I'm disappointed, but I am waiting for the batteries to discharge and recharge so I can try that option.
OK I just have to update this.

I now feel that the Trends TA10.1 is the best amplifier that I've ever owned. It's in another league, completely, from the NAD. Big sound stage, stable, big images, gobs of detail.

I'm out of town but will likely post a review of this when I'm back. If anyone wants to discuss how awesome the Trends TA 10.1 is, feel free to e-mail. I'm thrilled!
