In the beginning of John’s “reign” as chief Grado, which took place in 1990, the company was hurting with as little as $300,000 in sales. In fact, before John took over, Joseph Grado was very close to closing the doors of his beloved company. John remarked how the late 80’s and early 90’s were the market lows for both headphones and cartridges. Redbook had fully unseated vinyl at this point and Sony’s “Walkman” craze was clearly established and in fact, the “Discman” was out and it too was catching on and the kids sure weren’t turning to vinyl! At this point as well, DAC’s started to become quite proficient and with tricks like upsampling and oversampling, CD players started to actually sound good! Even with the poorly mixed and mastered recordings of the 1980’s! This speaks nothing of the increased proficiency in digital mixing and mastering after ten years playing with the media. It seemed even audiophiles started to dump their turntables in favour of a good cd player. Grado began as a cartridge manufacturer and eventually moved into turntable manufacturing as well as producing tonearms and speakers. Yet, in 1963, everything was dropped save for cartridges. With Joseph’s invention of the stereo moving coil cartridge, he was able to refine this design such that true audiophile grade carts were available to the world. They sold like hotcakes and the decision was made to focus on what was working and selling best. What was best then seemed certainly to be the death-blow to one of the oldest family-run audio manufacturers in the world, and one of the most innovative audio companies period . Perhaps to help sales out, Joe Grado had begun designing a very high-end headphone to be used in recording studios near the end of his tenure at Grado. This signature series which we all know and love as the HP-1000 series was actually never meant to be called the “HP-1000 series.” In fact, Joe had created the HP-1’s which were then called HP-1000’s. That was to be the only headphone Joseph ever designed; however, during the building process, (btw, it was John who built every single one of them, and there were only 1000 TOTAL, not 1000 of each type but 1000 of the HP-1000’s that’s it that’s all!!!) they tried building an HP-1000 without the phase switch. This was a much easier build (John holds a special place in his heart for the HP-1’s, but I don’t think that is a , those phase switches were a PITA to assemble and atvery good place present he is the only one who knows how to fix any problems with them) process yet all of the cups had already been screened with HP-1000, so the decision was made to call the HP-1000’s with the phase switch the HP-1’s, the HP-2’s the ones without and the HP-3’s the ones wherein the drivers were not matched as closely. The end result would be a revolutionary line of audiophile-grade but more important truly pro-grade dynamic headphones called the HP-1000 Signature Series.
As an aside, is anyone interested in knowing how to tell HP-2’s and HP-3’s apart? No? Okay, I won’t spill the beans on that. Oh what’s that I hear? Some threats of castration? Heh, no need to get all uppity and everything! The answer is…..on the underside of the pads, just like we tell the production number of the Reference series and the Pro series! On each HP-3, it was clearly marked HP-3. This HP-3 is easily rubbed off though. Ah crap then…how can we really know if someone can just rub it off? Well, for one thing, only 50 HP-3’s were ever made! Yep, that is a fact! The number is 50 max, likely less. The first batch of drivers were not as closely matched as possible (where the matching of the drivers was less than the .05 db) and so the decision was made to sell them at a cut below the HP-2’s. These would be paired up and shipped out as HP-3’s. However, on the later runs, the drivers were all able to be matched to .05 db. Therefore what was sold as HP-3’s were usually HP-2’s. That means, of the 50, the majority are up to HP-2 spec anyway, or in a word, HP-2’s rebadged. For those of you with definitive HP-3’s, John said he could not tell the difference in most trials between any of the models. The HP-3’s are so close or dead on exactly like the HP-1’s or 2’s. Another thing, the HP-1’s and 2’s, sound identical to him as well. There should be no difference in the sound at all. The only difference in sound should be equated with the cables if at all. Regarding cables, and this is interesting…only TWO cables were ever produced for the Signature series. The first is the Standard Joseph Grado Signature Cable, and then the second generation or the Joseph Grado Ultra-Wide Bandwidth Signature Reference Cable. But waittaminute…what about those HP-1000’s that came with a cable without any writing on it? Those, folks, are equipped with the RS-1 cable. Some of the phones had to be recabled and those that were, were recabled using the newest cable. I find it very very interesting that those who have heard all three cables have nearly unanimously agreed that the unmarked cable is the best. How many times have I read that Joe was the master and that much was lost on his apprentice John? Could it be that in fact, John does know what he is doing and that as I already stated, the priorities and/or goals are simply distinct? What is also important is that John was working full-time at Grado during the development of the HP-1000’s. Having assembled each and every one, he is keenly aware of their build quality, the production costs and most importantly, their sound. Above all, it was during the production of these HP-1000’s that John took over the company. I think I’m back on track now, aside finished.
确切的说HP3才是最罕见的型号呢
