Speakers for metal, hard rock ... also SS amp
Not doubting the excellent recommend's above... ...for serious metallic applications go for JBL (home -- not pro) recommended above. OR and IF your room allows use of corners or close, try big Klipsch (used). Or even TAD with appropriate subwoof.N... 
300b, x45, 211, etc.
Well, I can give you a reductionist, and highly subjective rigmarole based on limited experience with products sporting 300b, 211, 845, 2a3.All tubes can be usefully operated in a no-feedback circuit. Good stability. So, basically they're VERY goo... 
harmonic distortion and frequency response
I think you are asking about a few things. 3rd order linear & non-linear distortion: this is very often encountered when a SS amp is pushed beyond its energy providing capabilities (the amp is "clipping"): the resulting sound will be compresse... 
300b, x45, 211, etc.
Your question is perplexing: what exactly do you want to know?? The product differences? There are very many products using the tubes you mention... The difference between the tubes?? If so, it's difficult to say much more than that the 211 is mor... 
Sonus Faber Extrema vs. Guarneri
Extrema, no doubt. But the others are less expensive to both buy and operate (i.e. amplification and set-up). 
DIY Interconnects review
Here's an experiment very roughly based on JD's design -- VERY successful!Details: 24awg (0,4mm) enameled copper wire, each pole spaced 1,9mm apart (as per JD), standard WBT rca connectors; wire is soldered onto the rca, used pieces of cotton rope... 
Difficult Sopranos
"Her Royal Icy Highness, Princess Turandot". Try Callas/Schwarzkopf/Serafin on EMI or Sutherland/ Pavarotti/ Caballe /Zubi Mehta on Decca. (performance wise, I prefer the former to the latter) If I remember correctly, there's no (or little) over l... 
"Integrated Amp" Do I dare go there??????
Sure you can. Assuming you don't need gobs of power, there are many excellent products out there.However, outperforming yr present system is another matter, as I don't know what it is.Other than the itch and the obvious advantage of 1 pair less IC... 
ARC LS1, LS2, LS3 , or LS7, which to buy?
Regarding ARC, I can't remember myself thrilled with any offerings; as John (jafox) I had singled out sp10. The 9 wasn't bad -- but I believe this opinion was linked to its much more reasonable asking price rather than performance...Not intent on ... 
Kits - How to Get Started
Also consider Hagerman's kits. Before you tackle any kit, Google soldering or check [url+http://www.geocities.com/mistertippy/howto/desolder.html]here[/url]. Practise on any trashed component you find. 
Many reviewers will lead you down the wrong path.
Audio reviewing is done for entertainment purposes -- NOT for providing guidelines to interested parties.It also seems to help the hi-end industry by keeping its products in the limelight (weak as this light may be).Otherwise, why would most revie... 
Replacement Power Supply Capacitors for SS amps
Nichicon, Panasonic, Jensen, Sanyo... they're power supply caps fer chrissakes. Couple them with the usual "bypass" formula.What's wrong with yr present caps??? 
B&W 801 separate amplifier just for bass drivers
You can use two different amps -- as long as their input sensitivity is the same. I can't recommend specific products as I don't know the cut-off frequency of the mid-highs.Of course, we assume your preamp has no trouble driving two parallel loads? 
Starting a high-end audio shop... Am I crazy?
I am actually thinking of giving up a $120,000 yr job and starting a high-end audio retail biz - both online and hopefully later on a brick & mortar storeFrom a business point of view, and assuming you don;t have a revolutionary business-model... 
DIY Interconnects review
Well, JD, thanks once again, a legendary posting! (It's been a long time since your "Winter's lessons" -- remember that post years ago?).I have been experimenting with diy IC's along similar lines -- but in no way as thorough as you.Finances permi...
