Roger Skoff: “A cool half million dollars for a pair of speakers! Certainly impressive, but is it sustainable” Well, the question about sustainability and reference to the Death Spiral is a good one. However I have more interesting question to ask: w...

[quote user="Gregm"] Just a thought: sound reproduction, which includes main & harmonics, is what... sound reproduction is all about. The idea of performing reproduction in a consistent or with "structural integrity" manner is welcome -- bu...

[quote user="Romy the Cat"]The contemporary productions DHT tubes (Russian of Chinese) are superbly firm and have no internal noise when they shacked or hit. The mintage 60 years old tubes what you make the “close to ears” test responses like as some...

While it is rare that any component under "review" will be panned outright, it is not uncommon for the "reviewer" to refer obliquely to the component's flaws. In some cases, the flaws may even be presented or offered up as "features", or it may...

I suppose this further erodes my "credibility" regarding the "tube sockets" hysteria, but it is what it is, so here goes:Today I finally had the right combination of alone time and motivation (not to mention great electricity) and I got around to swa...

[quote user="steverino"]Again I would ask people who are reporting problems to state whether they have the original PP or the Plus version made in the last few years. One issue that is definitely tied to the Plus version was the overheating that a NZ...

Interesting. I think that with testing just for:
- gain - bias - distortion - power output - hum level balance
It is not necessary give an objective picture about resources of a tube. We can monitor the change rate in the tube bias as some ...

Hi Romy,
It was good to finally meet you at CES at the Cogent Room. I guess that you really found Steve and Rich's drivers pretty interesting (you initially wanted to buy a pair of the midrange drivers, remember?) It would seem from all the activi...

[quote user="jeff1225"] …"whatever that means" is that most rooms at a trade show are not good. You know this Rommy, I've seen you write it in past posts. [/quote] Shure, Jeff, I know what most rooms, if not all, at a trade show are not suppose to be...

Angelo,
I do not take your project seriously because of multiple reasons. I would not go into discussions about it as I fell it is unnecessary. Sill I will give you a tip, use if disregard it – it up to you. Forgot about S2, or any other “vintage” o...

Hmmm...let's see, I'm pretty young, to the point where I don't have any major source of money income, so I do with what I can when I can and want to, just like many other suffering young and/or poor audiophiles. It's like this, I don't listen to any ...

I thought the B1 was Yamaha's V-FET and the B2 was a later "hybrid", but I suppose both are Vintage Sufferer's wet dreams. I have never heard either amp, anyway.
Yamaha B1 and B2 conceptually the same amp. B1 is made only with one polarity V-...

It is excellent that Timbre is described here as color. This is actually how musicians speak about it. The problem with the comparison to photography is that color with a musical instrument is a moving target. If we take my own instrument, the trumpe...

[quote user="Patrick Mattucci"] Some say that we have better materials used in bearings and tonearms and cantilevers. We have better stylii today than we did in the 70's and 80's. When it comes to cartridges, I'm about 90% in agreement that today's a...

Thank you for the kind intro to your technician.
Yes, replacing the TL-0 will probably be a heartbreaking exercise. Just like there are people who own a few vintage Jaguars to cannibalize parts from one to the other, it is crazy...

The whole presentation of sound is very different with your and my file. Your file is very lush sounding. It is very pleasant but a bit too euphoric for THIS music. My file is much more dynamic (if comes from my transformer) and in the way this dynam...

I did one such newsletter many years ago at university; one description I recall was "have you ever - inadvertently or otherwise - tasted your own earwax? Well, embrace and amplify that thought, add tannins that could strip paint at five paces and ga...

I absolutely agree; whilst one's palate does expand its capacities over time, and whilst experience leads wine professionals to - on the whole - be able to predict what a young wine will do, I know that I myself cannot usefully taste more than about ...

[quote user="Paul S"]For one thing, I've already spent several decades charting vintage and newer "special" drivers and sound. [/quote]
I wish I had all that time to experiment.

The whole room (L-shaped) is larger as you all noticed, but as Roman saw in my Blog , the listening space is smaller - i.e. about 6,5 x 4,5 meters with low 2,70 ceiling - and is a perennial work in progress... yes, the Stereo Lab 1000 hz is a true wa...

I used to have a few musician friends and played a little myself, but they were never really interested in audio, they did have a system but no intention to sit in the sweetspot or anything of the sort, we used to go to concerts and they would carry...

Hi Romy,I have a couple of theories as to why I wasn't able to get to the "VTA sweatspot" before I tried the microscope method. The first is that my "baseline" (using the ice skate tool that wally sold me) was so far off that the range I was workin...

If I bought a case of a good wine and loved it and so then bought 3 cases of the next vintage because I was assured it was better year and the wine arrived and I tasted the wine and it was horrible I'd be upset also.

Not too many of the cheaper horns have really interested me so far, but I think that we here should help others with this as it could better help them have some horns and horn interest in general. I haven't payed too much attention to much ...

You are very much correct. All existing critical mass of knowledge and practices about hors is completely irrelevant for a home use and partially if user’s demands are more evolved then a typically-Moronic: “look the saxophone sounds like the real on...

[quote user="Romy the Cat"]What do you mean the example of inductive Lpad? All speaker level Lpads are inductive. The speaker level Lpads work with low voltage and high current and therefore they use wire wound restive elements. Any wire wound compon...
