There are over 20,000 FDA approved drugs. The majority of them will do nothing, some will have adverse side affects, and some can be life altering. Audio tweaks are the same, it depends on the patient/system. .
The magnitude of the skating force will be higher with a traditional overhung tonearm with an offset angle when compared to an underhung tonearm with no offset. With an underhung tonearm, the rotation torque (skating force) is generated only by the tracking angle not been inline with the pivot...
The Classic 3 was not designed to accommodate a 12” tonearm due to the lack of plinth space. VPI later produced the Classic 4 (larger footprint) that could accommodate a 12” tonearm.
Can the $250 deposit be applied to anything in the store? If yes, then I would pay for a demo and if the demo did not materialize into a sale of said products, I would simple buy $250 worth of albums, accessories, software etc. When I visit a B&M and listen to some equipment, I always buy a...
90% of the time, the hum is caused by an improper tonearm cable shielding, therefore, allowing for potential RFI/EMI contamination. The VPI tonearm/cartridge wires are enclosed in a copper tube within the 3D printed arm wand. The copper tube is attached by a small wire to the tonearm’s metal...
You need to be careful purchasing 1578 tubes as many NOS sold are actually rejects that did not pass quality control. Some tube dealers will go as far as re-inking the quality control OTK stamp on the metal base. Remember, back in the Cold War days nothing was thrown out. Also, it is...
I own both 70’s and 80’s tubes. The difference is in the plate construction. 1970’s production typically have shinny T-plates and tubes manufactured in the 80s have dull T-plates. Imho, there is very little difference between the two with a slight edge going to the shinny plates based on my...
Thomask, congrats on acquiring a pair of 1578. Looking forward to your full review. The 1578 tube is very detailed and does not smear the instruments together. Some would call this “air”. Imho, the 1578 does not have any short comings. It has a deep bass, fully fleshed out midrange and a...
With respect to the 1578 tube, the date is acid etched at the 6 o’clock position within the Melz factory stamp. The first two are Roman numerals denoting the week of manufactured followed by the year. I posted a picture (difficult to picture) but you ca clearly see the “76”. Hope that helps
A lot of comments regarding the Melz 1578 sounding hot in the treble can be attributed to the early (50’s and 60’s) regular nickel base 6H8C which is often mistaken for a 1578.
Regardless of other people’s impressions, you will soon be able to offer your own informed opinion once your 1578...
I’ve been rolling 6sn7 tubes for years and own or have owned almost all the tubes mentioned on this thread. The Tung Sol bgrp are a very nice tubes and I really wanted them to be the holly grail for the price I paid, but they ended up just being a very nice sounding tube.
My favourite 6sn7...
I currently have quite a few pair of 845. In order of preference:
1. 1941 RCA 845.
2. 1959 United 845W with the JAN-CUE designation and with the getter capsule
These two are the best. To my ears, I like the RCA a touch better than the United, but often swap back and forth with various...
Late 50's early 60's Mullard Blackburn factory made f32 fat base GZ34 are my go to rectifiers. Imho, same sound performance as the much more expensive metal base Mullard/Philips tubes.
It's not necessarily the criticism but the manner in which it is offered that offends people.
I don't like chocolate, therefore, chocolate sucks and you are an idiot for liking it and you know nothing about the culinary arts.
I use the XTR Di2 on my Intense T275 which has a 1x11 drive train. The gear changes are instantaneous and extremely quick. You can dump a lot of gears much quicker than a mechanical. So far I have had no problems with mud, dirt and rain. Personally, I would not invest the money in the Di2 for...
Just the opposite, Fatbikes are almost the opposite of a DH rig.
Production Fatbikes have pretty middle of the road MTB geometries that are good for XC riding and plowing through snow, sand, loose gravel, roots, mud etc. They don’t have the super slack angles of an all mountain rig. As the...
Mountain bikes are now designed to appeal to two groups 1) Gravity 2) XC with sub groups in between (Enduro, All Mountain etc.) There are advantages and disadvantage to "any" wheel size.
26 inch Bikes
Can be made lighter, stiffer and stronger than other sizes
Loads of existing 26in...
I absolutely love the 650b (27.5) wheel size for aggressive riding (Enduro, All Mountain, and Downhill). The bike tracks better than a 26 and does not loose any "flickability" of the former 26". I though that my former Transition Covert (pictured below) was the best All Mountain bike until I...
The Trek Session 9.9 is an awesome bike. I was a long time Trek fan (still am) and ran a Trek Session 88 in 2012 and a Session 9.9 in 2013. Here are a couple of pix.
It looks like VPI will be launching a new magnetic drive version of the Avenger table. Set to launch at the 2015 Capital Audio Fest.

Most acoustic feedback that excites the stylus is caused by low level energy from the speaker just outside the audible range. Try installing a rumble/subsonic filter to eliminate said energy.
