the SR-007 sounds soooo weird coming out of a 252s. there's literally a hole in 7.5k and it can barely do 40-50hz.

007 are very unforgiving and require very high quality amplification in order to bring out its potential. I think the BHSE with 007 is still one of the benchmark for electrostatic until today although the 007 also did a great job with my Iceland magic box (carbon). I guess it sound awesome with a T2.

yeah i know haha, i was just trying it out for kicks and was surprised at how poor it was. does anyone know why it performs so much worse though (like, in terms of electronics?) is it the bias voltage not being high enough?

 

[elton7033]

i think its because of voltage but even with my 727A the 007 didn't sound that great but the 009/S did a lot better with the 727

the 007s need a powerful energizer to shine... the 252s... are definitely not powerful.

ah, shame - I was watching a good condition SR-007mk1 on ebay and it went for $1650. did anyone here pick it up?

I have some sr-007 Mk2s with sz3-1700+ serial number that I bought used a year ago. I opened them up to do a blu-tack mod. These were not ported. I have had older mk2s so I know where the port is and what it looks like. In the case of these they are solid in that area (no port). I have been trying to search for information on this big change and at what serial it might have happened at. I got to thinking, I guess someone could have changed out the plastic frame where the port would be, but that doesn't seem likely to me. Long story short - anyone else come across a non-ported sz3 "2.9"?

Whoever did, that a pretty decent price. As I feel the Mk1 more closely matches the Harman curves more so than even the port modded MK2 and MK2.9 etc. Base on all the Harman curve graphs I've seen on all the 007 variants.

007mkI has -8.5db at 2800hz compared to harman curve, 007 mkII's 2800hz is -5db. 007mkI is, however, closer to harman curve after 4khz compared to mk2.9.

I was thinking of getting it (i actually had 5% ebay bucks too..) but I decided not to because I'm a little short on funds with the holidays and all maybe next time. that being said i'm pretty happy with my 007mk1 even though it's pretty scuffed - if I could just figure out how to recable it safely it'll be good as new

if you are planning to buy from ebay you should also look out for yahoo japan auction I saw one sold last 3 weeks for 120000yen which is about 1200usd. you can import it using through a agent, you normally need to pay for service charge and shipping but still cheaper than ebay.

since I am not a technical person, I have no idea on words but I will learn how to read measurement one day if someone teaches me. yea the 007Omega2 sounds a bit more natural compare to the 007A on my ears, but i have no idea how the graph present them lol

ah, wow. yeah, i currently use proxy service for japan (japan is where i got my SR-007), but didn't think i could find any new SR-007s. i'll keep an eye out!

I swear to god there was a thread in head-fi about recabling the SR-009, but I can't find it - anyone know where it's hiding?

007A sounds colored in mids because of the 1-1.5khz honk/shout. The purpose of spring mod is to eliminate that.

What Hifi Review of the sr-L700 if anyone is interested

Apologies if this doesn't belong here, but I thought it best to go to the source. I recently bought an SRM-T1S and enjoyed it very much for about two weeks until the left side went 99% dead. Took it to Mike Check audio here in LA and he discovered that the K389 transistor was the culprit. He and I both can only find them in China right now, so I was wondering if a) anyone has a tip on a North American source b) has a spare in their own personal connection or c) could suggest a suitable (or better) replacement. I will email Birgir as well.

Thanks for any tips.
