I bought my daughter a Fiio E7 for Christmas last year. I paid $60 for it. It has a Wolfson WM8740 inside and flawlessly plays up to 24/96.

So what that have to do with anything. . Have you even heard the amplifier? It  isa great product that has an issue that is being addressed. Comparing  budget gear to a product you have not even heard makes little sense.  The product  has an issue and many other high end expensive products released have had issues and the company is addressing them.  The HDVD800 works flawlessly on 24/96 files. Usually people who comment have at least heard the products they comment on.  Has Microsoft ever issued a operating system that worked flawlessly? Sennheiser is a respected company that will get it right. 

 

I also seem to remember issues when other flagship products were introduced such as the Stax 009 and that has been resolved.   I believe Sennheiser will get this squared away and everyone will be satisfied. I am waiting to finish a review and will do that when the DAC has a solution.

I just hope they fix the issue software wise (might be driver issue) so I don't have to send back the hdvd800 if I would ever stop using my V800 (which is very unlikely but still).

Only that Fiio is able to release a $60 product with a DAC that works.

 

Sennheiser got the hype wagon rolling on this amp a long time ago and should have ensured that it worked properly out of the gate. But yes, other companies do this too so I'm not blaming Sennhesier completely for this.

 

My main problem with this amp/Sennhesier is that there is still a lot of smoke and mirrors surrounding this amp. You say its a Burr Brown DAC but how do you know? Their website doesnt list this nor does the downloadable product sheet. The online technical data lists only Freq Response and THD. What is the output impednace? Someone posted 43 ohms but where did that number come from? How much power does it put into different loads? Again, not to be found.

 

I would expect this kind of thing from some snake oil boutique company, but not Sennhesier. Sorry, but it offends me.

 

For your review, here is the online tech specs page for the 4 Violectric amps. Cut and pasted from the Violectric website...

I dont need you to forward me specs for my review of other products that have nothing to do with the product I am reviewing. I also cant see why it offends you since you have no financial investment in this product. The people who have put their money up are having  less of an issue  than you and other people like you who have either never heard it or cannot or would not buy it anyway. The people who own this product are overall very satisfied with how  the product performs except the issue that Sennheiser is addressing and will have a solution for.  You posting other company specifications has nothing to do with this issue that  being discussed.

 

It seem like you have an agenda here. What it is makes very little or no sense since you have not purchased or even heard the product.   I also seem to remember you starting another issue regarding tubes amps in general and regarding other flagship products you never heard or owned.  In any event the problem is being addressed by Sennheiser.   What ever your motive is you certainly have no reason to be offended since you do not own this product.

 

By the way the review I am doing is not on a Violectric amp. I also see you do not own the products you are sending specs for

My odac/O2 has a similar list of specs and I sold my v200/800 because I prefer the sound of the hdvd800 with my HD800s . I do like measurements to confirm that I am listening to a brilliant amp on an objective level but I've had or own some if the best measuring amps yet I like this better . Maybe it's because it looks nice and says sennheiser on it. I hope they get a fix in place quick just so it's less of an excuse for people to bash this lovely sounding combo.
post #1058 of 2508
It actually says a lot about how good a product is when it has some issues and yet I would still keep it and be more than happy regardless .
post #1059 of 2508
I kept my v800 but sold my v200. Need a separate dac for my speakers anyway, but I do prefer the sennheiser amp over the v200

You misunderstand me.

 

I posted the Violectric specs to illustrate how a reputable company informs consumers about it's products so an informed decision can be made.

 

I have no agenda. I'm only stating my disappointment that Sennheiser, a company well known for its engineering prowess, is for some reason avoiding posting specifications for this product. As a reviewer, I am surprised that you are not bothered by the lack of information out there. Didnt you say yourself that they have not returned your emails and getting specs from Sennheiser has been like pulling teeth?

Hmmm...

Im sure it sounds great and is a fine product. And Im not saying that specs are everything. But the ear/brain is easily fooled by emotion (hence all the FOTM threads here), and I guess Ive been burned one time too many by snake oil vendors and was expecting more from Sennheiser.

 

EDIT: For me, red flags go off when I see a very high price, little technical data, and read flowery emotional reviews with little substance.

 

The HDVD800 is a high-end product from a company renowned for its professional grade studio gear. The most logical competition for the HDVD800 in my opinion is the Grace Audio M903 and Benchmark DAC2. Looking at the Grace and Benchmark websites, I get the impression of companies that really stand behind their products and have the utmost confidence in their performance and quality. I don't get that from Sennheiser on the HDVD800 - and it disappoints me. Im an HD 800 owner and would love to pair them with a Sennheiser amp of that caliber.

What has the receiver specifications  have to do with this thread. Everyone knows they have released limited information on the amplifier and that is their choice for whatever reason they have for not releasing the product specification sheet. It is a consumer choice to either buy it or not buy it. The products sound excellent and is one of the very best solid state amps I have heard and also up to 24 96 hz it is a terrific dac. If you are a consumer who buys products on spec sheet s then this is not for you. If you like many others buy for sound quality this is a great amplifier and once they fix the issue will also be a great amp/dac combo. The HDVa600 does not have the dac and the amplifier is identical and it sounds great.

 

Because they have not released a product sheet still takes nothing away form how this amplifier performs and it does perform in my opinion in the top tier of all solid state amplifiers I have heard.  As a reviewer I review what is presented to me for my opinion. I have expressed my feeling to Sennheiser and have been told they will be getting me that information and until the product issue is resolve  the review need to be on hold anyway.  When it all said an drone I believe they will release the information on this amplifier.   I think we just need to let Sennheiser do their thing.

I can see where you are coming from now palmfish and understand entirely. I like objective information and usually only go on specs backed up by opinion. For some reason I did things different this time and trusted my own ears which I know are only as good as my brain will allow and it is a bias fickle thing.i have no regrets with this amp and even after a few weeks of use and now knowing it has issues I still really like it. I am intrigued to see how it measures and i hope Someone measures it soon because I'm very confident it will be right up there with benchmark levels of performance.

Everything.

 

The HDVD800 is a $2000 box of mystery.

 

Im a PC Gamer and when I buy/build a PC, I want to know what processor it has. How much RAM, How big a power supply, What video card it has, cooling system, etc... Its not enough to read a couple of reviews that say it has a neon blue lit window and Bioshock looks really good with fantastic shadow detail and textures.

 

And again, Sennheiser is a company founded on audio engineering excellence. Its the foundation of their reputation. Why would the "choose" to not publish specs this time?

That is your right as a consumer and for others it is irrelevant. It all boils down to what consumers want to do and that will be determined by the marketplace of any product that is being sold.    You posting specifications on a pA system still has nothing to do with this thread. You made your point and now it time for this thread to get back on topic. Derailing this thread any further is pointless.
