Hi Saffy,

In response to your questions:

1. Both the Druid and Abbys are great speakers, especially Abbys for the money. I think the two do really well in small to medium sized rooms. Both benefit greatly from a subwoofer. Although, the Druids deliver surprisingly deep bass for a cabinet that is only 6.5" deep, really perplexing how they do that.

Zu seems to be one of those products that evoke strong responses, both pro and con. Some of those who dislike them have actually heard them, a lot have not. You have to decide for yourself and Zu's 30-day money back guarantee assures just that. Not many other manufacturers are that generous.

Oddly, we tried my PX-25 with Abbys but actually preferred the $800 Almarro A205A with it. The A205A is a single-ended pentode (SEP) amp that has sonic performance leagues beyond it's price. Paired with the Abby, it is sublime when you take cost into consideration. A few cheap upgrades to the Almarro make it a real giant killer.

As for other speaker options, please let us know your room dimensions, average listening level, and how far you sit away?

2. Low-power, high sensitivity, systems are far more revealing(IMO) to component and cables changes than high powered systems. Noise is also a big problem. For example, when I had 90dB speakers, my system was dead quiet. But, when i switched to 97dB speakers and <8wpc SETs, it became glaringly clear that I had a loud 60Hz hum problem in my household electrical system. The hum was clearly audible at my listening position 14+ feet away. I had to re-ground my breaker panel and then use balanced isolation transformers before my audio system before I could get it truly quiet. Never knew the noise was there with 90dB speakers.

I've also found that cable changes are far more pronounced with the high-eff system.

3. If you only have one source, then no need for a linestage. Whether the PX-25 passive will work well for you is really dependent on the output of your cd/turntable/tuner, etc. The PX has an input sensitivity of 0.7V, so anything with 1.5V output will do really well as long as you keep interconnects short. I probably wouldn't use anything that has under 1.2V output, a little headroom is always good so that the sources output stage isn't stressed at all - they distort badly when pushed hard.
I think you are making very good choises, I heard the Zu sounding very good, maybe at it's best, and thought it a great speaker at any price. I also agree that cable distinctions become much more pronounced as eff increases.
Thank you

My room:
-23 x 20'
-Speakers centered on 23'side(in front of wall of glass doors)
-Wood floors
-9'ceilling
-Sunken room with one 20' side completely open to th rest of the house
-listening distance 12-13' away

DAC: Meitner Bidat 3.5v output

-My idea would be test the Druids, if a go get the Px-25, and assume the Druids pass despite border-line bass - add their sub down the road.

1- Has anyone heard the Druids with the PX-25?
2-I would be auditioning the Druids with my Jadis 60w - could that prove misleading as to the eventual sound of the PX-25 combo?
3-I have a long 15' speaker cable run - is that a problem with 6w? They are efficient cables
4-At $5000.00 for the Druid sub combo - does that new budget open up some CLEARLY better sp. options

Nice digital front end, Saffy. I have the Museatex/Meitner Bitstream dac(3V/300ohm output) which had full signal & power supply upgrades by John Wright of Museatex in Nov 2005. Definitely works extremely well with the PX-25 and high-eff speakers. Also, plenty of drive for a passive preamp, I use an S&B TVC.
Saffy,This is from some old fart that's heard a lot of stuff! Find a great dynamic speaker that has a benign impedance(4 0hm,6ohm,or8ohm). Doesn't matter which impedance as long as it don't dance up and down. It needs to be at least 90 db at one watt. If you have a great preamp(active tube) then get a pair of Melody M2A3 Monoblocks. If you don't have a great pre. then I'd suggest the I2A3 amp(integrated version). They're 18 watts per channel and are nice. With the speakers i've suggested, you can still try a 300B SET (you'll just have to stay under 93DB). You can still have a nice solid state amp for when you want to party and just jam out! But, there is no amp that will do it all! I've found that the 2A3 push/pull gives me all the midrange magic of a 300B SET plus great bass and extended highs. Build your system to be able to convert to any style you wish and are in the mood for! The best and easy way to do this is make everything else work around the choosen amp for the moment or mood!
