I tried many portable amps/dacs and bottom line is get the FULL size amp, skip all the portable gears, portable doesn't even come close to full size.

If you can get used Burson Soloist/HA series it enhance the subbass.

Remember, it's not DAY and NIGHT difference

Vintage integrated amps or receivers really make these sing as well, and at a very good price. This is my main D7000 feeder.....

My Denon AH-D7000 and Pioneer SX-D7000 pairing use to really swing..

Nice rack! I wish I could find a setup like that for sale locally, though I am hesitant to go vintage after my bad experiences with my first vintage amp.

Do tell. I now have seven and the only one that needed any attention is the Spec 2 amp at the bottom of the rack in the picture.

Late 70's Optonica amp (back when they were making gear to compete with the big boys), everything is big and overbuilt, sounds great, pretty rare, haven't found anyone else with the exact same model (SM-4000U US plugs). Worked decently for awhile with reasonably sensitive speakers at moderate volumes. One of the channels started kicking out intermittently, sent it in for repair, they couldn't reproduce the issue and returned it to me without doing anything, but still charged me for looking around in it (which is pretty standard). Maybe 6 months later a drunk friend of a friend cranked it to a bit over 12-1 O'clock (which isn't that high, though admittedly the tone controls were set to a bit extra bass which would increase power needs) and the amp stopped working. Sent it to a shop and paid about $200 (I paid $165 for the whole amp) for him to screw around and install the incorrect output transistors in them (but they were an expensive matching pair! Good thing I was there to pick up the bill on that! /s) which broke pretty quickly. Then I gave it to a friend to fix up and recap (a member of Audiokarma, he does amazing work) and after paying for all that all was well for about a month (this was about a year ago) the left channel started fizzing in the high end at lower volumes. It still does this, no one can figure out what is causing it and most people can't reproduce the problem. It's been either in the shop or out of commission for longer than it's been working, and my computer still doesn't have a functional stereo (hooked up to a pair of B&W 685's as a nearfield computer setup and secondary system). I also have an Emotiva stack powering my Thiels that has been working beautifully since I got it. I also have the comfort of a 5 year warranty and very attentive customer support.

 

I really do like vintage amps, and it I had the money I'd probably have a bunch of them (so many pretty amps, I've always been a fan of Spec stacks like yours, plus you get both looks and sound quality for far cheaper than any modern setup). This experience, however, has left me pretty sour to the idea, and it's why I decided I had to buy a new amp and pre that had a warranty on it just for the added support and peace of mind.

 

By the way, are those Cerwin Vegas? Do you have other speakers you cycle in or are those the speakers that go with that stack?

Hmm...emailed Fostex Corp. asking for the driver replacement (for the D7K using the TH900 drivers).  Corporate said to get in touch with U.S. distributor.  Got in touch with the US distributor (American Music and Sound).  The distributor saying that they will need to send the 'phones back to corporate for the repair/replacement.  So, not too sure how to obtain parts for a diy fix.  Anyone else has any luck tracking down a replacement driver, either D7K or TH900?

That sounds like it would sour anyone on old stuff! Sorry you had such a challenging time. Optonica made great stuff.

Yes, they are Cerwin Vega DX-3's (10" driver). Got them a few months ago from a friend who knew I was looking for them - he found them at a garage sale for $20. I had them refoamed recently as the thumping and age (they are mid-70's speakers) and they sound great, and do what CV's are known for - bring the bass. Sound great in general as well so not just one trick ponies. I also rotate in a pair of Klipsch KG 3.2's that I like a lot but prefer the Cerwin Vega's for sure.

Yeah, and I totally understand that my experience is a pretty huge outlier. The amp is absolutely wonderful when it works and I just recently cleaned the faceplate and knobs so it's damn pretty right now. One other complaint that I'd make is that those switches are not strong enough, they stick out just waiting to get knocked or brushed against, where they'll bend pretty badly (of course, you can straighten them pretty easily but a couple very light knocks and they would probably break off).

 

That's cool, you use them for parties, or just rocking out? Also, if you mind me asking, what did you pay for your Spec stack? Those are usually a decent investment when you can actually find one.

I love the drama in these threads. Who needs Foxtel?

$270. Total. Right place, right time with the owner in need of $. To be honest no speakers were included or turntable. I use the system in my music/computer room upstairs. Have a 46" flat screen as well In the room as well as my wife and my computer desks. Spend a fair amount of time up there listening to the system as you'd imagine.
