One small bonus: great balance between left and right channel after checking with SPL meter
Great imaging and soundstage, excellent excellent balance from top to bottom
But I never expected these $20 a pair G.E. tubes to have the best overall tonal balance across the frequency range
There is no need to spend $$70 on three different driver tubes that I tried including a pair of Sylvania driver tubes I picked up for $14.These G.E. tubes are really great and have a terrific full sound as well as great tonal balance

This seller is awesome - they go out of their way to put test measurements on each tube box and the packaging keeps them totally protected during shipping
LP3 belt drive automatic turntable (read my Amazon review)Ortofon 2M Red cartridge (great basic cartridge)Polk Audio T15 Bookshelf speakers (good speakers in a small package)Monoprice 8” 60 watt powered subwoofer (tiny, but powerful)This package, together, is an unbeatable budget system for those just starting out in vinyl or for those who are returning to the vinyl world.

It's a great way to control the sound when you're not working with anything else.
I absolutely love the way they sound in this amp
If you want an effective, inexpensive way to see if tubes are for you, this is a great way to see if it's worth the expense.

My buddie also bought all the tubes I mentioned as well as a pair of Vostek and a second but different pair of Mullards to see if they could top the G.E's and not a single matched pair out of 5 different pairs of tubes could beat out the G.E. tubes sold here for $20.So to save you the trouble of guessing at the best driver
Great replacement driver tubes for the 6J1 pair that come with the Little Dot Mk II.
They are by far the cheapest price point and they are also the best sounding driver tubes I could get my hands on!
Hope this review helps out a few people looking for the best driver tubes and ignored these because they are G.E. tubes from America, where tubes are not known for great sound
MKII.That said the G.E. tubes were by far the best sounding driver tubes out of the three pairs I bought and they were also by far the cheapest

They portray a seductive quality to the midrange along with outstanding image width, depth and specificity
Bass was clearer and more pronounced while more complex music was more defined and with better imaging.
Great imaging and soundstage, excellent excellent balance from top to bottom
The amp is paired with Centrance Masterclass 2504's and has a very level soundstage with good imaging.

Greater bass response, no loss of detail (than the stock tubes), and everything is a bit clearer, broader frequency response
The original tubes sounded dry and lacked dynamic range, but these make everything sound more natural and improve bass response as well.
I can get great bass response from either headphone amp which is great
The mangi lacks good bass response and the Little Dot MK II does as well because it's a tube headphone amp

The tubes are very well matched, and the sound is excellent
I believe these tubes are the perfect match for my amp hooked to my Audeze Sine(planars) and ATH-ESW9A (dynamics)

I replaced some chinese 6j1 tubes with these and began to notice a significant difference after they had about 20 hours on them
Awesome tubes , noticeable difference from factory installed original tubes even 50 minutes of playing time !!

A very closely matched pair (2 tubes) of vintage US-manufactured GE JAN 5654W vacuum tubes
All tubes are Amplitrex TESTED and MATCHED
Both plate current and Gm are matched to within 3%
We subject these tubes to multiple test cycles and plate voltages to determine stability
In addition to ip, Gm, leakage/gas, noise and life testing, the matched tubes undergo a final audio sound check to make certain they are indeed audio quality
Tubes that show the slightest abnormality are rejected
With our high standards, less than 50% of the NOS 5654W tubes we test are considered for use in these special matched sets
5654W tubes were originally designed as a low noise premium-grade substitute for 6AK5 and EF95 vacuum tubes
The "W" designation refers to ruggedized, military grade, tubes; better quality control and internal design changes to enhance reliability and minimize microphonics/noise
This great sounding vintage tube has found new life as a replacement for 7-pin 6J1, 6J1P (6ZH1P-EV), 6AK5 and EF95 tubes and are commonly used by audiophiles looking for improved sound quality
All tubes selected for our tested/matched pairs will have identical date codes and are guaranteed to test at NOS levels of 5000 micro-mho or higher and a plate current (ip) of 7.2 mA or higher
(Tested in fixed-bias mode at a plate and screen voltage of 120 V and a grid voltage of -2.0 V)
All NOS GE 5654W tubes tested/matched by Riverstone Audio are GUARANTEED to test at NOS levels when received
**PLEASE NOTE** 5654W tubes are 7-pin and can ONLY be used to replace 6AK5, EF95, 6J1 / 6J1P tubes
DO NOT use to replace any other type of tube
***Certain amplifiers, such as the Little Dot 1+, MK II and MK III models may require circuit board jumpers to be changed when swapping tubes (this procedure is outlined in the Little Dot manual).*** As a US seller we stand behind our products and back our Platinum Grade tubes with a no-nonsense 1-YEAR WARRANTY - the BEST warranty in the audio tube business!
