Reliability issues with VTL amps/pre-amps
If you look at VTL schematics you will see they are very simple and intrinsically reliable, operating the output tubes at low current. However they use a high anode voltage and the choice of output tubes is critical - if you take Albert Porter rec... 
Avantgarde Duos - right for me?
Did anybody try the Dartzeel electronics with Avantgarde Speakers? 
A Conrad Johnson pre for cj amp
Although it will cost around usd 1500 second hand the cj Premier fourteen is a bargain - you get the same input selector and Vishay volume attenuator as used in their top preamps and the gain stage, based in a triode gain - cathode follower topolo... 
Audio Research Ref: CD8
76doublebass, Can you tell us what cables and amplifier were being used in this system?My CD8 is now approaching the target of 600 hours burn in. As soon as it stabilizes I will compare it to the old CD7. 
Speaker cables for Sonus Faber Extrema
Great speakers. Are you using them with tubes or solid state?Long ago - perhaps more than 10 years ago - I used them with XLO signature 5.1 and later Transparent Reference XL - Forsell CD combo, cj ART and Krell KSA300s. They could not play at low... 
Amp rec for AR REF3/CD7, & SF Auditor M's/REL B2
I can only support Elberoth2 recommendation. Once you own the CD7/Ref3 combo it is not easy to find better than the Ref110 without great expenditure. Sometime ago our local Ayre distributor brought the monoblocks for a short hearing in my system a... 
Jadis JA30 - Quad ESL63 .. 4,8 or 16ohms?
4est, you are discussinging the Quad ESL63 with the same ideas that are usually applied to electrostatics such as SoundLab and Martin Logan, but the ESL 63 is a different case. SoundLab and MartinLogan have impedances that can be as low as 1 ohm, ... 
Audiophile quality variacs to decrease voltage?
The performance of any power conditioner depends on the quality of the device and mains quality. Most of the time people wisely complain about Variac performance being poor because they are referring to the usual low quality high power types used ... 
Jadis JA30 - Quad ESL63 .. 4,8 or 16ohms?
Sorry to disagree, but the ESL63 has an impedance that increases with sound level in the bass. At levels over 100mV the impedance never drops bellow 8 ohm in the bass. People usually measure impedance with a 1000 ohm series resistor, using levels ...

My CD8 has been now been playing almost continuously for 22 days approaching 500 hours. Happy to tell that after burn in the bright, sometimes almost edgy sound is completely gone.During the burn in phase I had to remove the Valhalla cables from m... 
Audiophile quality variacs to decrease voltage?
You do not need an autotransformer. Just buy a 115 - 9V transformer (I think 3A, 30W will be enough for your power amplifier) and wire the secondary in series with the mains feeding your amplifier. If you connect it the proper way you get 124-9 = ... 
Audio Research Ref: CD8
Hi, I have fitted myself the two tube upgrade kit to my old CD7 and did not find it deteriorated the sound - truth is it did not change, compared to a good set of matched 6h30. Later a close friend also had it fitted to his player by the distribut... 
Avantgarde Duos - right for me?
I have very little experience with horns. Some years ago I tried to listen to some Avantgarde, but as the dealer setup was poor I was not impressed and gave up the idea. However at the 2008 Lisbon Hifishow I heard a pair of Nano's driven by a smal... 
Audio Research Ref: CD8
Although it is still too early to have a definitive opinion - my CD8 has only around 250 hours continuous playing time with same breaks - it is now very different sounding from the CD7. The sound balance is different, the CD8 bass has better defin... 
Cable to amp for Cj Premier 16
It is dangerous to suggest a cable without knowing the full system, but I have successfully used the Shunyata Antares and Transparent Audio cables with an ACT2 and a premier 350.
