Is Singled Ended a con?

Here is a quote from tle Lenard Audio website
http://www.lenardaudio.com/education/14_valve_amps.html
Myths and facts. To appreciate valve technology we must first be-bunk audiophile myths that in-correctly describe them. Many Audiophiles believe in alchemy and behave similar to religious cults. Cult driven audiophiles are easily identified by their repetitious chanting of brand names, model numbers and meaningless superlatives concocted by high priest reviewers and marketing departments. The highest Deity worshiped by the occult audiophile is the Single ended Class A valve amplifier. These amplifiers have one 1930s style large triode per channel. They are extremely in-efficient, average 3 to 20 Watts and often generate excessive 2nd harmonic distortion. The reason for worshiping one output valve, is same reason the religions of Abraham worship one God. These single ended amplifiers can be decorated with gold, and interconnected with oxygen free cable which channels Orgone energy (un-used sexual energy) from the lost city of Atlantis, enabling anything connected to the cable to transcend the laws of physics. Many of these cult objects are faddish nonsense and a few are beautiful works of art. The right pic is the KronzillaSX amplifier by KRaudio.
Audionote has a range of single ended amplifier DIY kits showing their internal construction.

Some single ended valve amplifiers today, including replications of early triode valves are made by enthusiasts demonstrating the craft and skills similar to enthusiasts who replicate old grandfather clocks and steam engines. Some of these hand crafted single ended amplifiers are highly valued by collectors and as stated earlier can be beautiful works of art. This craft of demonstrating the skills to create technology of the past must not be confused with modern technology and science.

Trevor Lees speakers

You know how every now and then something surprises you? We have just set up a pair of Trev Lees’ 2 way speakers and all of us were really impressed. Using an inverted Focal tweeter and what looks like a Seas 8 inch woofer they put out and impressive sound- quick and accurate with ample bass extension. And all this for under $500. Worth hearing.

“Stereophile”

While looking up the Krell KAV 300i on the ‘net I saw Stereophile have an offer if you subscribe. Click in 12 months and a window opens offering you an extra 12 months pretty cheap. In Australia I paid $47.97 for 24 issues. I will keep you posted on my impressions.

Note Perfect speakers

A pair of Mike Kontor’s biggest speakers are in the shop to sell on behalf of a club member.
We know that they were delivered new with Morel midrange drivers, but were upgraded by Ron N, the well known crossover expert to Vifa and a passive radiator.

More on the Melbourne Audio Club 17 March meeting

Mohan and members of the Audio Guild (Lowther club) demonstrated some of the best sounding equipment we’ve heard recently. Duc’s Commonwealth turntable with Reed arm and Zyx Airy cartridge sounded great using Duc’s Valve phono stage and 2A3 SET amp (2W).
Altec 15″ 416Bs in Onken cabinets, mids Altec 288c with 1005 multicellular horns, and JBL 2495 for high frequencies all creating a highly dynamic sound, not often heard these days.
If you think 2W single ended is not enough power for the Willis room you are right. The sound was fabulous, but the 2W output was struggling on some peaks. The music was chosen to show off the wide dynamic range, one of the highlights was Lighning Hopkins blues recorded in 1963. It makes one wonder why so many modern recordings seem incapable of capturing natural sound!

Krell and Aranov

Two new integrated amps have arrived. If you like the sweet and pure midrange that valves are renowned for, you must listen to this Aranov amp According to it’s owner it responds well to voice, can’t wait ot hear some good vocal jazz through it, coupled with B+W speakers perhaps.
At the same time a Krell 300i came into the shop. We’ve been listening to it through our reference Altec speakers. Plenty of grip, very clear and detailed, more listening tomorrow. This amp is sure to go soon, come in and listen while it’s still on demonstration.

Melbourne Audio Club and Audio Guild

Wednesday 17 March is a special night at the Melbourne Audio Club. Visitors from the Audio Guild (Lowther club) will be showing off some of the best sounding equipment in Australia.

Aronov LS-960i integrated amplifier

We have just received another Aronov product. The preamp we had recently has found an audiophile home, and this LS960 uses the same pre stage. The power output is 60Wpc, and the bass control is supposed to be awesome. I’ll confirm that later.
Sound stage .com say this “Yakov Aronov, the designer of all Aronov equipment, is an electrical engineer who manufactured his first amplifier in 1953. Through the years, he continued to design home and professional amplifiers with attention to sound quality and reliability. The Aronov LS-9100 amps are beautifully finished. Side panels are in a piano-black finish while the faceplate is black glass with a gold-plated logo backlit by a cool X-Files-like green light. A self-biasing quad set of Svetlana 6550C tubes and a single 6AN8 driver tube. The power supply and output transformer are massive.”
Price is expected to be in the $3700 range.
