Re. Modifying amps.

Given the talk about making modifications to existing amplifiers, this brings up an important point. It’s not intended as a knock against the HCA-2 specifically, but it’s just a fact about the difference between traditional manufacturers versus manufacturers that sell factory-direct. For any given price point, the “bill of materials” or parts cost will almost certainly be greater for a factory-direct component because, unlike the traditional manufacturer, they don’t need to worry about dealer markups. The dealer markup is significant, and can easily double the cost of a component, if not more. Consequently, the factory-direct manufacturer can either charge less or re-invest the savings into design improvements, including (but not limited to) better parts. That’s why manufacturers like Acoustic Reality (and others like VMPS, BPT, Bent Audio, Don Morrison Audio, etc.) have an advantage -- their cost structure allows them to compromise less on basic things like component quality so consequently they can get away with using superior parts while keeping prices reasonable. Finally, since they don’t scrimp on parts quality, you won’t see aftermarket modders fiddling with their innards.
Oxia is right. Mods can help a lot of components, and not others. To Oxia's list I would add Pass Labs, a whole seller. Through building a great reputation, they have been able to enjoy steady sales that support a lot of research and development. Changing a single item in their X amps would spell disaster for their clean solid state sound.
Oxia, I think you are missing the point. Virtually every product can be improved. Case in point; your eAr amp. Acoustic Reality has improved their circuit or so they say.

I guess Peter has been fiddling around with his own design and improved it.

If you check the Acoustic Reality website you can see if you have the latest upgrade. If you don't, you can send it back for the "modded" circuit upgrade.

Although from the customer sevice nightmares many have experienced from Peter and Acoustic Reality you might be better off keeping the lesser eAR version.

And give it time, modders somewhere will probably find a way to even improve the eAR. Progress and perfomance never stand still.
Fiddler,

I see your point, but I think you've missed mine. I don't doubt that there will be design improvements in the future for even the most accomplished of components. After all, the "best" never sit on their laurels. And I'm also aware of the eAR upgrade too. What I was trying to say in my earlier post is:

1. For a given price point, factory-direct offerings tend to have higher value for the dollar, because money that's saved by avoiding dealer markups can be put into higher quality parts.

2. Straight-forward parts swapping may yield benefits when the quality of the parts were compromised in order to meet a price point. However, this wouldn't be necessary (and may even have negative results) if the parts quality wasn't compromised to begin with.

As a consequence of these two beliefs, I've tended to seek out factory-direct alternatives to the usual gear found in brick-and-mortar shops. I'm not advocating it for everyone. It's certainly safer to take the road that's more travelled, but it's my choice and it has served me well.

PS: My service experience with Acoustic Reality so far has been exemplary. I had my eAR upgraded from MKI to MKII specs last year (the change allowed me to use conventionally terminated speaker cables rather than SPEAKON plugs), and the amp was turned around without a hitch.
Oxia, you and I are in complete agreement. I have purchased most of my gear factory-direct online for two reasons. The first being that I agree with your assessment that factory-direct companies are better bang-for-the-buck.

Secondly, I live on Maui and there are zero brick & mortar audio shops here. But even if there were, I would still probably prefer factory direct.

I have not heard the Acoustic Reality amps, but I am sure they are very good. I believe digital is certainly the wave of the future. I said that the minute I listened to the HCA-2 stock.

I also believe digital is in it's infancy, including the Acoustic Reality products. I suspect in a few years we may possibly hear things from digital products we didn't think possible. But having said that, I anticipate in early '05 I will be auditioning equipment to overhaul my entire system. At that time I plan on auditioning Tenors, Berning, Goldmund, etc., so I haven't completely written off tubes as evidenced by the Tenors and Berning.

As good as Spectron & Acoustic Reality may be (and I would love to compare both to my modded HCA-2), I suspect that the likes of the amps that I mentioned above are still in a different league. Five years from now, as digital really begins to mature, it may be a different story. But currently I still believe (admittedly, without hearing them) that digital amps may still be bettered with high-end conventional designs. I will find out in a year or so.
