Our new flagship amp with triodes 211 in push-pull configuration, “Dual Class A” and “PAB autobias”.
90W in Class A – 250W in class AB. Comes as a pair of power mono-blocks
WE NOW OFFER FULL BLACK VERSION. LIKE IN UPACKING VIDEO BELOW. If you don’t want to watch the video entirely, just go the the last minute.
These power blocks are simply incredible. They will offer you the better sound money can buy for this range of products.
You may think that $3,799 is quite an amount of money, but these blocks are a true bargain regarding sound performance and construction quality. We are proud to say that you simply won’t find similar sound performance on the market below $10,000.
The DOGE 9 “2014 version” (produced until December 2014) were great. These DOGE 9 PAB go one step further with several improvement.
First of all, don’t think that these power blocks are targeted only for users who need high power. Whether you need just 50W or even 20W, these power amps will deliver a better sound than any integrated amp of this range of power. They have not been designed for power performance first, but with the core idea that they should deliver a marvelous sound performance. Even if you would use them never above 30W, they will delight your ears.
So why making them so power efficient ? We simply thought that if these speakers would deliver 250W with reasonable distortion, they would have an extremly low distortion at 50W. It is the case as they rate 0.08% distortion at 50W which is simply incredible for triodes.
The advantage of their high power, is that they can match with all speakers on the market, including the ones requiring high current, and with all kind of listening rooms, including very large ones. But even you have a small listening room (which is the case of most of Doge 9 owners), these power blocks will deliver the best sound performance among all our products.
About our new DUAL CLASS A mode :
What is fantastic is with the new Doge 9 PAB compared to the 2014 version, is that in this newest version we have 3 amplifiers in one.
The first one is in true class A with 80mA anode current and deliver 90W, the second is the same as Doge 9 “2014” and deliver 150W RMS in class AB The last one deliver 250W RMS in class AB2. The small difference between these two last classes is that class AB2 has slightly higher distortion.
To sum-up, you can really enjoy 150W RMS with a great gorgeous sound like the Doge 9 “2014” (RMS Watts are the only real Watts given by any Hifi respectable company) and in the same time to have benefit of a true class A with 90W. The change of mode just requires 1 mn to let the PAB processor reset the bias settings.
To reach this power, we use 5 transformers per block. Because five transformers might have cause some vibrations, we have deeply reinforced the chassis by making it with thick 8mm aluminum, which is a thickness you usually find only on front panels. In addition the part where stand the transformers is a of mix aluminum + steel. On the scale the result is simple, the weight per block is : 106 pounds or 48Kg.
Let’s talk now about sound performance.
Triode are unique in tubes audio. They have a warm and marvelous sound but their weakness is often their low power. With the Doge 9 push-pull configuration, the power is not anymore an issue.
These power amps use 2 famous 211 triode (also known at VT4C) in push-pull configuration. Some potential buyers might be a bit sceptical about the 211 because it is not a well known tube in Hifi. Indeed, if experienced audiophiles know well the 211, most of them might know better the triode 845. Actually the 211 and the 845 are sister triodes however the specification of 211 have been improved for military use. To make simple, the 211 is an improved version of 845 triodes. Then, if you like the sound of 845, you can only love the sound of the 211.
The sound stage is incredible. Especially on live recordings, you can really feel how far the singer is from you. In addition you have a triode typical sound, which means a warm and fluent sound without any aggression in mids or highs.
The input stage uses a 12AT7 triode in SRPP mode. The phase inverter stage use another 12AT7. The driver stage use a EL34 pentode per phase. The output stage is composed of two 211 tubes in push-pull configuration.
The DOGE 9 PAB is supplied with Psvane 211 Hifi Series which is a very good standard.
If you budget allows it, you can spoil you with the Psvane 211-TII which is one of the best 211 current productions and even face well compared to NOS. There is another tube which is it higher standard, the Psvane WE211, but this tube has been launched very recently, around early 2015, so that’s not even 3 years it is on the market. We don’t know have it will age, and that’s an important factor for an expensive tubes. The TII and Hifi series are now 6 years old, so we have more feedback.
These power amps are designed to be very safe amplifiers. If it happens that one tube would crash by accident, this amplifier has a very efficient Auto Protection Mode (APM). As a result the amps would automatically turn into stand-by mode.
– It has a Soft-Start function to increase tubes life span.
– It has an stand-by function, so you can turn them on from your sofa with the remote controller of our the Doge 8 preamp (a cable connection between Doge 8 preamp and Doge 9 is required).
– There is a fuse for the main power supply (built-in in main power female plug) and a second fuse specially for the main power transformer supplying high voltage. This, added to the auto-protection mode, make these blocks indestructible.
In 2013 we added to the Doge 9, a new function called the Doge FLS , for Feedback Loop Selector which allows the user to choose between two feedback loop modes. The low feedback mode will offer better sound, but requires very linear speakers at the output. The normal feedback mode is the same as it was before 2013 and is recommended with speakers who have less linear frequency response.
