I would personally avoid NVA, the requirements for usage in terms of cabling make it far too impractical - unless of course you want to buy an all NVA set-up.

There are no requirements for usage with a passive pre - NVA or otherwise. It's power amps & integrateds you need to be careful with - the Capacitance of I/Cs and speaker cable is important for these amps, which are designed for passive preamps.

Alan,
Too true. I experimented with a Glasshouse TVC passive last summer and whilst it gave me a glorious midrange it seriously screwed dynamics given the i/c lengths I had to use between the different coponents on different stands and the i/c lengths (rather expensive too) at the time. We live with whatever constraints we work with at any given time...
I'm sure that with smaller boxes working in closer proximity, I might have derived better overall results but then I'd have compromised the microphonic-reducing stand configuration I was using and still use. On balance, I prefered the rather expensive Spectral solid state pre I had at the time. This was soon replaced by anthonyTD's rather excellent active grounded grid pre giving me the best compromise of the two worlds of midband lucidity and dynamic contrast.
The sheer geography of setup as well as synergistic matching never ceases to make this hobby no less than incredibly fascinating, certainly if holism in pursuit of (recorded) musical enjoyment really is your thing.

I vaguely remeber that this question was asked a while ago but it looks like the posts were lost in the recent attack. I ran a few simulations on the PC and reported that bandwidth was OK unless you had a really high load. 7.5K was OK (2 x 15K i/p impedance amps as a load) but the phase started to change alarmingly after about 1 Khz would could be a real problem.
Note that a passive pre based on a volume pot is a totally different thing to a transformer based passive pre.

Mmmm... for what it's worth... I would prefer to buy the Creek Audio OBH-22 as it has a remote volume control but I am unsure about cabling and I do know this can be problematical. For power amp duties I am using a Samson Servo 600 studio amp into Dali Suite 2.8 speakers but my interconnects are Van Den Hul 102 III Hybrids. These have a very restrained treble already but it suits my delicate ears (lol) however I spend a lot of time listening to techno music as well as folk.
At the moment I am using the Samson's inbuilt gain pots on the front panel but find that I need some form of input switching so a passive pre with a remote volume pot could be the answer.
Shaun,
I thought you were looking at replacing your amp set-up?
If so, I'd wait until you've done that before worrying about passive pre-amps. You may render it useless!

I am indeed. There are so many variables though it's hard to keep track of them all. I like the Samson but it's not Hi-Fi is it...??? That is the main weakness. If I had around a grand behind me the choices would be so obvious but I am working to a 500 pound budget and that makes it much more difficult. I love valves but for techno...??? I am just not sure.
Does that mean I can offer my WD88XL on the 'open market' then?

I would dearly like to buy your amp. My last experience of WAD amps was stunning. As I have said though, at the moment I'm working to a budget of 500 pounds. You want 700 and I can't afford it right now. In a few months I will be able to. I simply need a bigger budget and that will come with time.
With the best of intentions I have so many people telling me so many things.
