I am very excite at the prospect of getting almost all of the performance of the HD800 from the HD700 I'm sure some aftermarket quality cables can increase performance even further - looking forward to hearing them soon!

Like you, I don't like the treble to be too hot, in fact I seem to be very sensitive to sharp treble and find it very unpleaseant. I once had a pair of Sennheiser HD595s, Sennheisers "Grado like" headphones, and found them unbearable and have stayed away from anything described as "detailed" since. The best non-bright non-harsh headphone I've heard is the Shure 1840, or even slightly better, the modded 1440 I've described. It's hard to find good HF detail without the brightness and peaks, but these two do a good job.

Non hifi bright, it's a job for orthodyanmics .............. Anyway, Live music treble is nothing to do with hifi bright and piercing. It's smooth, dynamic and surprisingly rounded like tube amps!

If it's bright and piercing, it aint HiFi !!! If it's surprisingly rounded like tube amps, it's because of typical tube amps HF rolloff !

That's why I noted the Shures. Neither bright/piercing nor rounded.

If it's surprisingly rounded like tube amps, it's because of typical tube amps HF rolloff! Just one of Audio Research ........... REF110 Specifications:FREQUENCY RESPONSE: ( -3dB at 1 watt) 0.6Hz to 90kHz. Even objective Prof Frans will be proud of .............. That's why he is into Sunrise and all that jazz now .............

You must have missed Frans recent post about valves in general. Frans will most likely design what there is a demand for by members, (within reason) provided that it isn't too expensive to construct.If Frans thought it was safe to do so, bearing in mind the safety of inexperienced constructors , the voltages used with his valve designs would further increase well past the almost double voltage of this new one.I suspect that Frans main motivation is to provide a much better alternative to the numerous flawed ebay offerings.

Other than the $$ motive, I don't think so even he is against tube. Check his Sunrise and later models specs. All more than within what he considered as good enough for audio frequency hifi. Do we need to go to MHz and even GHz to put filters to filter out the HF garbage to have better hifi? I don't think so. Maybe that's for you.

IMO,a reasonable 100kHz square wave response is adequate,which I think Frans has done with one of the new designs. HOWEVER, we aren't talking about VALVE amplifiers , we are talking about HYBRID designs here, not all valve, type amplifiers. Your beloved X-CAN V2 isn't a valve amplifier, it's just using a twin triode in place of a differential pair in an otherwise solid state design, even down to the use of normal rectifier diodes. It uses 7 transistors and 4 semiconductor diodes per channel, and more semiconductors in the PSU.

Actually, Chong I've been discussing valves with Frans because a cheap true valve amp that I have seems to bring up slight hf problems on my Denons.
One explanation could be the stuff added by valves is being detected by the headphone. I kind of hear a roll off but also very slight mushiness.
I don't get it with the V2 but that amp kind of uses a valve to 'flavour' the sound since the rest is in fact SS stuff!!
So it's not a full blown tube amp in fact. Still one of my favourites though.

Ok, go full valve and check their latest specs. The Audio Research is full valve and getting better and better as time goes. But nothing is better than hearing one and compare how far it is from Live, the standard hifi should be based on.

I did. I had a speaker system set up for me (!!) to try and review. The whole lot came to roughly £24,000 retail.
It was drop dead gorgeous but I managed to blow a valve. I nearly had a heart attack. I felt so guilty. All I did was turn it on. Luckily for me, the dealer just laughed and replaced it. The cost was ridiculous. The valve was bulb shaped - very strange.
Now that sounded good but it cost a bit more than a Bravo or V2.
However, it made me stop and think..... If you were going to spend £24,000 on a top end system ..... In your oft repeated words ...... Hi rezzzzz .......
Would you opt for tubes or solid state?
For me, it would be SS because of reliability and cost of maintenance.
However, at the silly low prices we buy most of our gear at, I don't mind taking a chance with valve gear.
Some of the things I've heard thanks to RG have been amazingly low priced for quality of sound but not really top end stuff.
Would you relax with an expensive valve system?

Would you relax with an expensive valve system? To be frank, I would go hybrid just because of the power tubes cost alone! However, full valves can also be an actuality depending on the power valves used and the number. If they are those std cheaper power valves and I'm using a lower power amp just for the high range in a triamp system, I will buy one. In the same triamp system, I will go for a hybrid or mosfet for the mid and transistor or Class D for the bass for obvious reason. The mid and bass amps will correspondingly be more powerful because of that reason. Anyway, I'm planning for a triamp system again when I'm earning again and a lower power full valve amp can be a possibility. But actually people playing expensive valve amps are in a completely different league altogather. They will likely be people owning a Porsche, Ferrari or Lambo or highend Merc and many properties. At least in Singapore. I think you are in that class in being a famous pop star, right? How come that 24k pound amps still hasn't belong to you yet? I don't think money is a consideration for your class. I wish I have made it like you.

Yeah, quite many reports said that it's as good or even better than the HD800. I have heard it - it is nowhere as good as the 800 - but it's a lot better than the 600 and 650.

The HD 700 is just starting to ship - Sennheiser UK had some in this morning.

Ah, at last heard one yesterday! Very good sound but soundstage not as big as the 800 and also doesn't have the feeling of extra property at the ears when worn. Just exactly. Overall, I prefer the 800 but if have to, I can also easily live with the 700. But please take note as this preview is only over 5 minutes and no direct comparison with the 800 but from memory of what I heard of the 800 as there is a long que to listen to the 700.
